It's not the paltry sums used for unemployment benefits or stimulus programs as the Regressives would have you believe. (Economists agree the best way to stimulate the economy is to provide continued unemployment benefits to those out of work.) People who have no jobs tend to SPEND EVERY DIME that comes in on things like food, electric, mortgage payments, etc., and put the money back into the system. But giving wealthy people special tax cuts just means they stash more away and invest more.
No, the real causes of the huge deficits are Bush's unnecessary tax cuts and the unnecessary wars. The chart shows, in light and dark brown, the real culprits of the record-breaking deficit.
