Modern Economics 101

In a nutshell:

The United States, of course, long ago captured first prize in the global arms race. It now spends as much as the next 14 countries combined, even as the spending of our rogue enemies and former enemies -- Cuba, Iran, Libya, North Korea, Sudan, and Syria -- much in the headlines for their prospective armaments, makes up a mere 1% of the world military budget. Still, when you're a military superpower focused on big-picture thinking, there's no time to dawdle on the details.
[...]
One principle has, by now, come to dominate our American world, even if nobody seems to notice: do whatever it takes to keep federal dollars flowing for weapons systems (and the wars that go with them). And don't count on the Pentagon to lend a hand by having a bake sale any time soon; don't expect it to voluntarily cut back on major weapons systems without finding others to take their place. If, as a result, our children are less likely to earn high school and college diplomas than we were, that's what prisons and the Marines are for.

War without end. There. Here. Everywhere.
