Except for foreign aid, which amounts to a pimple of spending, Americans don’t want to cut anything in the budget. Yet we want to cut the budget deficit for the simply sensible reason that it is unsustainable. The US is moving into dangerous ground for debt and deficits.
Politically, I believe that the only possible solution is to cut the whole budget by a set amount, say, 10%. In addition, a total freeze in spending across the board would lead to a balanced budget in just a few years.
