damn those wealthy leftists arguing against tax cuts!

I've been meaning to comment on this for a while, but it fell through the cracks. The International Herald Tribune's Raymond J. Keating rehearses the tax cuts spur the economy argument, claiming there will always be "wealthy leftists who understand their particular businesses quite well, but fail to grasp how the economy works or the critical role that wealth plays in our economic system." I wonder where Warren Buffet falls in Keating's taxonomy of economic thinkers. Buffet, as pointed out by Lambert on Eschaton, says that dividend tax cuts are welfare for the rich and a bad idea. I guess he must not understand "the critical role that wealth plays in our economic system." Or something.
