Not as instantly appealing to the eye as a (misleading) graph, but the below articles show some fundamental flaws in Hauser's Law (or at least how its misused to support supply side policies).

@ Mint----re: your last sentence: Word. You're right. I'll quibble about the distinction of professionals being among the relative few who've seen their income rise. You're absolutely correct there, but my point goes beyond that. When one looks at the concentration and explosion in wealth/income accumulated by those at the top in the last decade, we need to set aside any conception of "the top" here including doctors, lawyers, or other professionals that actually work for a living. Forget anything related to even Torie's income level of where upper middle class transitions into "merely rich". Forget the "top 2%/over $200k a year" bracket affected if the Bush tax cuts are repealed. We are talking about the upper few
tenths of a percent who have had their post tax income multiply by staggering amounts, both percentage wise and in raw dollars. The Kochs have become the bete noir in Wisconsin, but as billionaires they are actually typical of the real winners here.
