The world economy is dominated by people in governments who believe that printing money, burying it and paying people to dig it up again will increase the amount of trucks built and goods shipped. No amount of failure of this theory will be enough for it to be abandoned, because it has a certain amount of truthiness to it, and it excuses profligate and wasteful behaviour.

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."
