Much of the "growing inequality" of the U.S. comes from the fact that we are importing poor people. This is true independent of whether or not increased immigration is a bad thing; if you add poor people to the country, the nominal poverty rate will be higher even if everyone is better off, because the new poor people's incomes are suddenly figured into the statistics, and their previous lower incomes in their home countries are not counted.
Roert J. Samuelson makes this point in Newsweek, which is terribly important at a time when we are being told how awful our growing inequality problem is.
Thanx and a tip o' the hat to the VDARE blog.
That is all.
