> Since billionaires get that way by being better at investing, the theory that poor people inherently put money to better use is not persuasive.
The claim is that poor people’s use is better for society (positive externalities) not for the poor person. That billionaires are better at assuring that any negative impacts of their transactions are externalized, and insuring internalized gains, is clear, but not the point.
I’m saying that the fact that billionaires get to be billionaires by a combination of ability and inclination at maximizing their personal benefits from transactions, while true, doesn’t provide even slight counterevidence to the claim it was offered to rebut.
