Steve Sailer on Divisions of Intellect and Class

A big problem for modern class warriors like Pat Buchanan on the right or Jim Hightower on the left is that over the years the number of blue collar workers with the verbal talent needed to articulate their class interests has plummeted. Where'd the smart ones go? To college and then into white-collar jobs. In the past, unions and other working class institutions had leaders and spokesmen who were both highly intelligent and authentically representative of the rank and file.

This same kind of brain drain is evident in regional migrations. The smart kids move to the big cities and local leadership becomes ever more stultified.

Sailer's essay scores some other points. When human equality of capacity is presumed as a matter of fact, the moral imperative to use one's special talents for the good of the less fortunate becomes obscured. Everybody's equal, so people who aren't successful must have some culpable personal failing that kept them from success.
