Most Americans have yet to feel these costs. The price in blood has been paid by our voluntary military and by hired contractors. The price in treasure has, in a sense, been financed entirely by borrowing. Taxes have not been raised to pay for it -- in fact, taxes on the rich have actually fallen. Deficit spending gives the illusion that the laws of economics can be repealed, that we can have both guns and butter. But of course the laws are not repealed. The costs of the war are real even if they have been deferred, possibly to another generation.
