Has the Everything Store become a dangerous monopoly threatening the U.S. economy?
Some time later this year, Amazon could become the first trillion-dollar company in American history. Its valuation has already doubled in the last 14 months to about $800 billion, and Jeff Bezos, its founder and CEO, is officially the richest man on the planet.
There are ways in which Amazon seems to be the greatest company in American history. It’s revolutionized the global shopping experience and expanded into media and hardware, while operating on razor-thin margins that have astonished critics. But some now consider it the modern incarnation of a railroad monopoly, a logistics behemoth using its scale to destroy competition.
So what is Amazon: brilliant, dangerous, or both? That’s the subject of the latest episode of Crazy/Genius, our new podcast on technology and culture.
To build the case for breaking up the Everything Store, I talk to Scott Galloway, a professor of marketing at NYU and an outspoken critic of big tech, and Lina Khan, a researcher at the Open Markets Institute and a leading expert on antitrust policy. Both of them encourage me to see how a company famous for low prices can still behave in an anticompetitive manner. Making the case against heavy regulation for Amazon are Rob Atkinson, the president of the Information Technology and Innovation Foundation, a tech think tank, and Michael Mandel, an economist with the Progressive Policy Institute who researches technology and e-commerce. Both encourage me to focus not only on the hidden costs of Amazon’s largeness, but also on the hidden benefits.
Last weekend, Steelers running back Le’Veon Bell sat out the first game of the regular season rather than play under the NFL franchise tag. Slated to earn $14.5 million in guaranteed money in 2018, Bell loses out on $855,529 each week he fails to report. The franchise tag would make Bell the third highest paid running back in the NFL this season — but only if he actually plays. Around the league, there is a wide range of speculation on how long Bell’s holdout will last. ESPN’s Adam Schefter reports that his sources believe Bell could be back by the end of September, while others note his holdout could conceivably last through Week 10.
Harvard Professor Clayton Christensen has said that half of all colleges will go bankrupt. The problem is, there's no evidence that's true. Only the supposedly innovative, disruptive for-profit ones are going under.
The outrageous price of a U.S. degree is unique in the world.
“I used to joke that I could just take all my papers and statistical programs and globally replace hospitals with schools, doctors with teachers and patients with students,” says Dartmouth College’s Douglas Staiger, one of the few U.S. economists who studies both education and health care.
Both systems are more market driven than in just about any other country, which makes them more innovative—but also less coherent and more exploitive. Hospitals and colleges charge different prices to different people, rendering both systems bewilderingly complex, Staiger notes. It is very hard for regular people to make informed decisions about either, and yet few decisions could be more important.
In both cases, the most vulnerable people tend to make less-than-ideal decisions. For example, among high-achieving, low-income students (who have grades and test scores that put them in the top 4 percent of U.S. students and would be eligible for generous financial aid at elite colleges), the vast majority apply to no selective colleges at all, according to research by Caroline Hoxby and Christopher Avery. “Ironically, these students are often paying more to go to a nonselective four-year college or even a community college than they would pay to go to the most selective, most resource-rich institutions in the United States,” as Hoxby told NPR.

IN WATCHING the flow of events over the past decade or so, it is hard to avoid the feeling that something very fundamental has happened in world history. The past year has seen a flood of articles commemorating the end of the Cold War, and the fact that "peace" seems to be breaking out in many regions of the world. Most of these analyses lack any larger conceptual framework for distinguishing between what is essential and what is contingent or accidental in world history, and are predictably superficial. If Mr. Gorbachev were ousted from the Kremlin or a new Ayatollah proclaimed the millennium from a desolate Middle Eastern capital, these same commentators would scramble to announce the rebirth of a new era of conflict.
And yet, all of these people sense dimly that there is some larger process at work, a process that gives coherence and order to the daily headlines. The twentieth century saw the developed world descend into a paroxysm of ideological violence, as liberalism contended first with the remnants of absolutism, then bolshevism and fascism, and finally an updated Marxism that threatened to lead to the ultimate apocalypse of nuclear war. But the century that began full of self-confidence in the ultimate triumph of Western liberal democracy seems at its close to be returning full circle to where it started: not to an "end of ideology" or a convergence between capitalism and socialism, as earlier predicted, but to an unabashed victory of economic and political liberalism.

Building on this, could we create a list of governments and empires and rank them in order of the length of their spans? There may be subtleties in changes of regimes in some eras, but generally things are probably reasonably well laid out. I wonder if the length of life of particular governments follows a power law? One would suspect it might. ❧

What we may be witnessing is not just the end of the Cold War, or the passing of a particular period of postwar history, but the end of history as such: that is, the end point of mankind’s ideological evolution and the universalization of Western liberal democracy as the final form of human government. ❧

Believing that there was no more work for philosophers as well, since Hegel (correctly understood) had already achieved absolute knowledge, Kojève left teaching after the war and spent the remainder of his life working as a bureaucrat in the European Economic Community, until his death in 1968. ❧

But whether a highly productive modern industrial society chooses to spend 3 or 7 percent of its GNP on defense rather than consumption is entirely a matter of that society’s political priorities, which are in turn determined in the realm of consciousness. ❧
It’s not so much the percentage on produced defense goods, but how quickly could a society ramp up production of goods, services, and people to defend itself compared to the militaries of its potential aggressors.
In particular, most of the effort should go to the innovation side of war materiel. The innovation of the atomic bomb is a particularly nice example in that as a result of conceptualizing and then executing on it it allowed the US to win the war in the Pacific and hasten the end of war in Europe. Even if we otherwise had massive stockpiles of people or other weapons, our enemies could potentially have equaled them and dragged the war on interminably. It was the unknown unknown via innovation that unseated Japan and could potentially do the same to us based on innovation coming out of almost any country in the modern age.

Weber notes that according to any economic theory that posited man as a rational profit-maximizer, raising the piece-work rate should increase labor productivity. But in fact, in many traditional peasant communities, raising the piece-work rate actually had the opposite effect of lowering labor productivity: at the higher rate, a peasant accustomed to earning two and one-half marks per day found he could earn the same amount by working less, and did so because he valued leisure more than income. The choices of leisure over income, or of the militaristic life of the Spartan hoplite over the wealth of the Athenian trader, or even the ascetic life of the early capitalist entrepreneur over that of a traditional leisured aristocrat, cannot possibly be explained by the impersonal working of material forces, ❧
Science could learn something from this. Science is too far focused on the idealized positive outcomes that it isn’t paying attention to the negative outcomes and using that to better define its outline or overall shape. We need to define a scientific opportunity cost and apply it to the negative side of research to better understand and define what we’re searching for.
Of course, how can we define a new scientific method (or amend/extend it) to better take into account negative results–particularly in an age when so many results aren’t even reproducible?

Hence it did not matter to Kojève that the consciousness of the postwar generation of Europeans had not been universalized throughout the world; if ideological development had in fact ended, the homogenous state would eventually become victorious throughout the material world. ❧
This presupposes that homeostasis could ever be achieved.
One thinks of phrases like “The future is here, it just isn’t evenly distributed.” But everything we know about systems and evolving systems often indicates that homeostasis isn’t necessarily a good thing. In many cases, it means eventual “death” instead of evolving towards a longer term lifespan. Again, here Kauffmann’s ideas about co-evolving systems and evolving landscapes may provide some guidance. What if we’re just at a temporary local maximum, but changes in the landscape modify that fact? What then? Shouldn’t we be looking for other potential distant maxima as well?

But that state of consciousness that permits the growth of liberalism seems to stabilize in the way one would expect at the end of history if it is underwritten by the abundance of a modern free market economy. ❧

Churchill famously said “…democracy is the worst form of Government except for all those other forms that have been tried from time to time…”
Even within this quote it is implicit that there are many others. In some sense he’s admitting that we might possibly be at a local maximum but we’ve just not explored the spaces beyond the adjacent possible.

For our purposes, it matters very little what strange thoughts occur to people in Albania or Burkina Faso, for we are interested in what one could in some sense call the common ideological heritage of mankind. ❧
While this seems solid on it’s face, we don’t know what the future landscape will look like. What if climate change brings about massive destruction of homo sapiens? We need to be careful about how and why we explore both the adjacent possible as well as the distant possible. One day we may need them and our current local maximum may not serve us well.

After the war, it seemed to most people that German fascism as well as its other European and Asian variants were bound to self-destruct. There was no material reason why new fascist movements could not have sprung up again after the war in other locales, but for the fact that expansionist ultranationalism, with its promise of unending conflict leading to disastrous military defeat, had completely lost its appeal. The ruins of the Reich chancellery as well as the atomic bombs dropped on Hiroshima and Nagasaki killed this ideology on the level of consciousness as well as materially, and all of the pro-fascist movements spawned by the German and Japanese examples like the Peronist movement in Argentina or Subhas Chandra Bose’s Indian National Army withered after the war. ❧
And yet somehow we see these movements anew in America and around the world. What is the difference between then and now?

This is not to say that there are not rich people and poor people in the United States, or that the gap between them has not grown in recent years. But the root causes of economic inequality do not have to do with the underlying legal and social structure of our society, which remains fundamentally egalitarian and moderately redistributionist, so much as with the cultural and social characteristics of the groups that make it up, which are in turn the historical legacy of premodern conditions. ❧

Beginning with the famous third plenum of the Tenth Central Committee in 1978, the Chinese Communist party set about decollectivizing agriculture for the 800 million Chinese who still lived in the countryside. The role of the state in agriculture was reduced to that of a tax collector, while production of consumer goods was sharply increased in order to give peasants a taste of the universal homogenous state and thereby an incentive to work. The reform doubled Chinese grain output in only five years, and in the process created for Deng Xiaoping a solid political base from which he was able to extend the reform to other parts of the economy. Economic Statistics do not begin to describe the dynamism, initiative, and openness evident in China since the reform began. ❧

Here publishers are marketing to professors who assign particular textbooks and subverting students which are the actual market and consumers of those textbooks. This causes an inflated market and has allowed textbook prices to spiral out of control.
The American Health Care Market
In this example, the health care providers (doctors, hospitals, etc.) have been segmented away from their consumers (patients) by intermediary insurance companies which are driving the market to their own good rather than a free-er set of smaller (and importantly local) markets that would be composed of just the sellers and the buyers. As a result, the consumer of health care has no ability to put a particular price on what they’re receiving (and typically they rarely ever ask, even more so when they have insurance). This type of economic anomie is causing terrific havoc within the area.
(Aside: while the majority of health care markets is very small in size (by distance), I will submit that the advent of medical tourism does a bit to widen potential markets, but this segment of the market is tiny and very privileged in comparison.)
In a non-economic setting it also seems to be highly applicable to social media silos like Facebook, Twitter, et al as they break social norms. I’ll have to circle back to write a longer essay about this with regard to the IndieWeb movement.
The political scientist argues that the desire of identity groups for recognition is a key threat to liberalism.
I’m also reminded here of Mark Granovetter’s ideas that getting a job is more closely tied to who you know. One’s job is often very closely tied to their identity, and even more so when the link that got them their job was through a friend or acquaintance.
I suspect that Fukuyama has a relatively useful thesis, but perhaps it’s not tied together as logically and historically as Menand would prefer. The difficult thing here is that levels of personal identity on large scales is relatively unknown for most of human history. Tribalism and individuality are certainly pulling at the threads of liberal democracy lately. Perhaps it’s because of unfulfilled promises (in America at least) of the two party system? Now that we’ve reached a summit of economic plenty much quicker than the rest of the world (and they’re usurping some of our stability as the rest of the world tries to equilibrate), we need to add some additional security nets for the lesser advantaged. It really doesn’t cost very much and in turn does so much more for the greater good of the broader society.

Fukuyama’s argument was that, with the imminent collapse of the Soviet Union, the last ideological alternative to liberalism had been eliminated. ❧
“Last” in the sense of a big, modern threat. We’re still facing the threats of tribalism, which apparently have a strong pull.

The National Interest, as the name proclaims, is a realist foreign-policy journal. But Fukuyama’s premise was that nations do share a harmony of interests, and that their convergence on liberal political and economic models was mutually beneficial. Realism imagines nations to be in perpetual competition with one another; Fukuyama was saying that this was no longer going to be the case. ❧
And here is a bit of the flaw. Countries are still at least in competition with each other economically, at least until they’re all on equal footing from a modernity perspective.
We are definitely still in completion with China and large parts of Europe.

Rationality and transparency are the values of classical liberalism. Rationality and transparency are supposed to be what make free markets and democratic elections work. People understand how the system functions, and that allows them to make rational choices. ❧
But economically, we know there isn’t perfect knowledge or perfect rationality (see Tversky and Khaneman). There is rarely even perfect transparency either which makes things much harder, especially in a post-truth society apparenlty.

For Kojève, the key concept in Hegel’s “Phenomenology” was recognition. Human beings want the recognition of other human beings in order to become self-conscious—to know themselves as autonomous individuals. ❧
This is very reminiscent of Valerie Alexander’s talk last week about recognizing employees at work. How can liberal democracy take advantage of this?
August 27, 2018 at 10:53AM
Kojève thought that the other way was through labor. The slave achieves his sense of self by work that transforms the natural world into a human world. But the slave is driven to labor in the first place because of the master’s refusal to recognize him. This “master-slave dialectic” is the motor of human history, and human history comes to an end when there are no more masters or slaves, and all are recognized equally. ❧

For Adam Smith, wealth was related to the division of labor. As people and firms specialize in different activities, economic efficiency increases, suggesting that development is associated with an increase in the number of individual activities and with the complexity that emerges from the interactions between them. Here we develop a view of economic growth and development that gives a central role to the complexity of a country's economy by interpreting trade data as a bipartite network in which countries are connected to the products they export, and show that it is possible to quantify the complexity of a country's economy by characterizing the structure of this network. Furthermore, we show that the measures of complexity we derive are correlated with a country's level of income, and that deviations from this relationship are predictive of future growth. This suggests that countries tend to converge to the level of income dictated by the complexity of their productive structures, indicating that development efforts should focus on generating the conditions that would allow complexity to emerge to generate sustained growth and prosperity.
How behavior and institutions are affected by social relations is one of the classic questions of social theory. This paper concerns the extent to which economic action is embedded in structures of social relations, in modern industrial society. Although the usual neoclasical accounts provide an "undersocialized" or atomized-actor explanation of such action, reformist economists who attempt to bring social structure back in do so in the "oversocialized" way criticized by Dennis Wrong. Under-and oversocialized accounts are paradoxically similar in their neglect of ongoing structures of social relations, and a sophisticated account of economic action must consider its embeddedness in such structures. The argument in illustrated by a critique of Oliver Williamson's "markets and hierarchies" research program.
