Why Is The Middle Class Shrinking? by Steven Horwitz,
2 Arguments in Favor of Economic Inequality
Economic inequality continues to be a major political issue even as the headlines scream about terrorism and climate change. Bernie Sanders has made it a centerpiece of his presidential campaign, and other candidates have addressed it along the way. And a recent study by the Pew Research Center has added new, though misplaced, fuel to the fire of those concerned about inequality.
The Pew study has been discussed in the media, and one key point has been grossly misunderstood. Among other things, the study found that the American middle class is shrinking and is now just under half of the population. Commentators quickly began to refer to the “hollowing out” of the middle class and to tie this study to the concerns about growing inequality.

However, a close look at the data shows that the middle class has shrunk since 1971 because more members of the middle class have moved up the income ladder than down it.
Don’t believe me? Look for yourself at the terrific graphic that the Financial Times created to illustrate the data:
You can watch as the folks on the left slowly slide to the right over 44 years. When you compare the 1971 distribution with the 2015 one, what do you see? A growth in households earning around $80,000 or above, adjusted for inflation, since 1971 and a significant decline in those making less than that amount (with the exception of the folks right around $0). It’s true that there’s not a fat middle class anymore, but why should that trouble us if there are more high-income households and fewer low-income households overall?
The funny part of this is that if you read the story in the Financial Times that accompanies this graphic, it’s as if they never actually looked at the graphic they produced. Their narrative is at odds with it, as the narrative proclaims the doom-and-gloom story that the graphic actually refutes. As they say, never let the facts get in the way of a good story.
This growth in household income may, to some extent, be a by-product of the same economic processes that have produced the concerns about inequality, illustrated in this graphic by the significant growth of the ultra-rich.
There are far more very rich people today than there were 44 years ago, but the growth of the upper class has gone hand in hand with the enrichment of a large number of less-well-off households. Are there ways in which economic inequality is good, then? I think the answer to that question is yes. If so, then, what are they? Here are two defenses of economic inequality that proponents of the free market could make.
First is the more obvious one: growing inequality is good because it might be a consequence of economic institutions that produce all kinds of results that we think are desirable. For example, if competitive markets lead to peace and rising prosperity for all but also create inequality along the way by allowing some folks to get very rich, then we should at least tolerate that inequality because the things that produce it also produce other things we like.
This is the usual defense libertarians invoke, and it’s a good argument. The critic, however, might say that even if the defense is true, it doesn’t prove that inequality is necessary for that result. There’s a difference between saying, “Good economic institutions will produce inequality while creating good economic outcomes for all,” and saying, “Good economic outcomes for all can’t be produced without inequality.” The critic would likely ask how reducing the inequality that markets produce will harm their ability to produce those good results.
And here is where we come back to the Pew study and get a second defense of inequality. One way the middle class (and all of us) has become richer in the last generation is that the cost of so many goods and services has dropped in terms of the number of hours we have to work at the average wage in order to purchase them. The lower price of basic goods has enabled more and more people to afford things like large TVs, smartphones, and new, cheaper medications.
One thing that has made this process happen is inequality. In The Constitution of Liberty, F.A. Hayek argued,
A large part of the expenditure of the rich, though not intended for that end, thus serves to defray the cost of the experimentation with the new things that, as a result, can later be made available to the poor.… Even the poorest today owe their relative material well-being to the results of past inequality.
Having a group of very rich people is what enables yesterday’s luxuries to become today’s basics.
There are two parts to this process: cost bearing and discovery. The very rich are able to afford the high prices of new technologies, thereby providing an incentive for firms to market new and expensive products. Once the rich pay the high initial price and cover the fixed costs of research and development, sellers can begin to price closer to the much lower marginal cost of producing additional units, making the good much more affordable to more people.
But the rich are also an economic canary in the coal mine that informs producers whether they are getting it right.
For example, a critic of inequality might complain that no one “really needs” a $100,000 luxury car with all kinds of new high-tech gadgets on it. But the fact that some can afford it and want to buy it helps the car companies figure out which new features might be popular. Rear-view cameras were once only available on top-end cars, but they have slowly become a standard feature. The same may soon be true of collision warning systems now available on high-end models of some cars.
In fact, everything we think of as basics today was once the province of only the well-off. The first microwaves were expensive and bought mostly by the rich. I can remember my parents paying about $900 for a VCR in the late 1970s. VCRs, of course, fetch a price close to zero these days. The rich who bought the early LCD TVs helped manufacturers defray the fixed production costs and figure out what people wanted, and now these TVs are in the vast majority of houses at a more affordable price.
The inequality at any point in time is a key part of the process that creates wealth for the rest of society over the years to follow. The very rich enable producers to experiment and cover their costs, and that makes more goods more affordable for the rest of us, from fun toys to life-saving necessities.
The inequality produced by the market is a key part of how the market moves forward, enriching all of us in the process. And that’s why the middle class is shrinking: the rich, through the competitive market, have helped make the middle class richer.
