Well then I'm sure you considered "income" sheltered in tax-exempt "charitable" foundations that the extreme rich use to game regulations?

This most recent data from the IRS does not.

But, earlier data from the CBO doesn't use adjusted gross income: it uses total income from all sources (including transfer payments like the earned income credit). It also distributes corporate income and taxes among households according to their share of capital income:

US Federal taxes by income level 1979–2007

The resulting numbers aren't exactly the same, due to the differing basis. But, the trends are very similar.

I see also that you have ignored my point about tax-exempt foundations entirely.
