It's amazing to me how many people don't understand the simple genious of Keynes. Of course this works, it's what made the US the most prosperous country in history after the depression. It's been proven many times since. Demand for goods and services increases once people have money to spend regardless of how they earned it. In response to increased demand companies hire the people who dug the hole. Now more people have productive jobs and keep the economy churning. Like Richard Nixon said, "We are all keynsians now." That's because it works.
