The WSJ poses a tickler:
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.
Good luck to all of us, and God help our children.
