Even the most basic inspection of the IRS income tax statistics shows that raising taxes on the salaries, dividends and capital gains of those making more than $250,000 can’t possibly raise enough revenue to fund Mr. Obama’s new spending ambitions…

[A]s a thought experiment, let’s go all the way. A tax policy that confiscated 100% of the taxable income of everyone in America earning over $500,000 in 2006 would only have given Congress an extra $1.3 trillion in revenue. That’s less than half the 2006 federal budget of $2.7 trillion and looks tiny compared to the more than $4 trillion Congress will spend in fiscal 2010. Even taking every taxable “dime” of everyone earning more than $75,000 in 2006 would have barely yielded enough to cover that $4 trillion.

Fast forward to this year (and 2010) when the Wall Street meltdown and recession are going to mean far few taxpayers earning more than $500,000. Profits are plunging, businesses are cutting or eliminating dividends, hedge funds are rolling up, and, most of all, capital nationwide is on strike. Raising taxes now will thus yield far less revenue than it would have in 2006.
