People always seem to forget that money doesn't evaporate. Public expenditure usually gets ploughed directly into national and local economies. A quarter of it comes flying right back in direct tax revenue. The rest gets spent too. I'm not saying it couldn't have done that in a better way, educational bursaries, healthcare, etc but if you're looking at this from a purely economic standpoint, the US exports this stuff. Not something you can lump on some other causes.
