"in people who don't need it from a marginal consumption standpoint".

We need the rich to spend more money. There are plenty of cool ways to do this. Build a mile high pyramid on a Nevadan playa, a canal to the Sea of Cortez to re-flood the Salton Sea, humans on other planets, new city states a la Praxis, interstellar probes, etc.

Some billionaires are doing some of these things. Hope more do in the future.
