NYTimes: For Richer

American income equality has returned to the 1920's. Long but fascinating article, many points - including the influence on politics, excerpts below:

America before 1930 was a society in which a small number of very rich people controlled a large share of the nation's wealth. We became a middle-class society only after the concentration of income at the top dropped sharply during the New Deal, and especially during World War II. The economic historians Claudia Goldin and Robert Margo have dubbed the narrowing of income gaps during those years the Great Compression. Incomes then stayed fairly equally distributed until the 1970's: the rapid rise in incomes during the first postwar generation was very evenly spread across the population.

Over the past 30 years most people have seen only modest salary increases: the average annual salary in America, expressed in 1998 dollars (that is, adjusted for inflation), rose from $32,522 in 1970 to $35,864 in 1999. That's about a 10 percent increase over 29 years -- progress, but not much. Over the same period, however, according to Fortune magazine, the average real annual compensation of the top 100 C.E.O.'s went from $1.3 million -- 39 times the pay of an average worker -- to $37.5 million, more than 1,000 times the pay of ordinary workers.

n September the Senate debated a proposed measure that would impose a one-time capital gains tax on Americans who renounce their citizenship in order to avoid paying U.S. taxes. Senator Phil Gramm was not pleased, declaring that the proposal was ''right out of Nazi Germany.'' Pretty strong language, but no stronger than the metaphor Daniel Mitchell of the Heritage Foundation used, in an op-ed article in The Washington Times, to describe a bill designed to prevent corporations from rechartering abroad for tax purposes: Mitchell described this legislation as the ''Dred Scott tax bill,'' referring to the infamous 1857 Supreme Court ruling that required free states to return escaped slaves.

Twenty years ago, would a prominent senator have likened those who want wealthy people to pay taxes to Nazis? Would a member of a think tank with close ties to the administration have drawn a parallel between corporate taxation and slavery? I don't think so. The remarks by Gramm and Mitchell, while stronger than usual, were indicators of two huge changes in American politics. One is the growing polarization of our politics -- our politicians are less and less inclined to offer even the appearance of moderation. The other is the growing tendency of policy and policy makers to cater to the interests of the wealthy. And I mean the wealthy, not the merely well-off: only someone with a net worth of at least several million dollars is likely to find it worthwhile to become a tax exile.

It is no accident that strongly conservative views, views that militate against taxes on the rich, have spread even as the rich get richer compared with the rest of us: in addition to directly buying influence, money can be used to shape public perceptions. The liberal group People for the American Way's report on how conservative foundations have deployed vast sums to support think tanks, friendly media and other institutions that promote right-wing causes is titled ''Buying a Movement.''
