It's like the old Milton Friedman story told by Stephen Moore:

'At one of our dinners, Milton recalled traveling to an Asian country in the 1960s and visiting a worksite where a new canal was being built. He was shocked to see that, instead of modern tractors and earth movers, the workers had shovels. He asked why there were so few machines. The government bureaucrat explained: “You don’t understand. This is a jobs program.” To which Milton replied: “Oh, I thought you were trying to build a canal. If it’s jobs you want, then you should give these workers spoons, not shovels.”'

Cool story, but did Milton Friedman genuinely do in his head the optimization between the social benefit of the jobs program and the infrastructure benefit of the new canal?
