Warren's Testimony
I haven't read it yet.
Also, I disagree that people are equivalent to a reverse magic penny. They may squander their money and not build wealth from it. However, that money is mostly spent consuming which is leading to the growth of a company and/or the "better than average person" at growing wealth. This is probably equivalent, but not worse than, government spending on a bunch of useless purchases or the funding of a useless job for a person who will also squander their money.
