No More ’50s and ’60s

Few economists expect the country to return to the relatively flat income distribution of the 1950s and 1960s. Indeed, they say that inequality is likely to remain significantly greater than it was for most of the 20th century. The Obama administration has not proposed completely rewriting the rules for Wall Street or raising the top income-tax rate to anywhere near 70 percent, its level as recently as 1980. Market forces that have increased inequality, like globalization, are also not going away.

But economists say that the rich will probably not recover their losses immediately, as they did in the wake of the dot-com crash earlier this decade. That quick recovery came courtesy of a new bubble in stocks, which in 2007 were more expensive by some measures than they had been at any other point save the bull markets of the 1920s or 1990s. This time, analysts say, Wall Street seems unlikely to return soon to the extreme levels of borrowing that made such a bubble possible.

Any major shift in the financial status of the rich could have big implications. A drop in their income and wealth would complicate life for elite universities, museums and other institutions that received lavish donations in recent decades. Governments — federal and state — could struggle, too, because they rely heavily on the taxes paid by the affluent.

Perhaps the broadest question is what a hit to the wealthy would mean for the middle class and the poor. The best-known data on the rich comes from an analysis of Internal Revenue Service returns by Thomas Piketty and Emmanuel Saez, two economists. Their work shows that in the late 1970s, the cutoff to qualify for the highest-earning one ten-thousandth of households was roughly $2 million, in inflation-adjusted, pretax terms. By 2007, it had jumped to $11.5 million.

The gains for the merely affluent were also big, if not quite huge. The cutoff to be in the top 1 percent doubled since the late 1970s, to roughly $400,000.

By contrast, pay at the median — which was about $50,000 in 2007 — rose less than 20 percent, census data shows. Near the bottom of the income distribution, the increase was about 12 percent.

Some economists say they believe that the contrasting trends are unrelated. If anything, these economists say, any problems the wealthy have will trickle down, in the form of less charitable giving and less consumer spending. Over the last century, the worst years for the rich were the early 1930s, the heart of the Great Depression.
