"If you take an economics course, they’ll teach you, correctly, that if the government spends n dollars to stimulate the economy, it doesn’t really matter what it’s spent on: they can build jet planes, they can bury it in the sand and get people to dig for it, they can build roads and houses, they can do all sorts of things—in terms of stimulating the economy, the economic effects are not all that different.² In fact, it’s perfectly likely that military spending is actually a less efficient stimulus than social spending, for all kinds of reasons. But the problem is, spending for civilian purposes has negative side effects. For one thing, it interferes with managerial prerogatives. The money that’s funneled through the Pentagon system is just a straight gift to the corporate manager, it’s like saying, “I’ll buy anything you produce, and I’ll pay for the research and development, and if you can make any profits, fine.” From the point of view of the corporate manager, that’s optimal. But if the government started producing anything that business might be able to sell directly to the commercial market, then it would be interfering with corporate profit-making. Production of waste—of expensive, useless machinery—is not an interference: nobody else is going to produce B-2 bombers, right? So that’s one point."
