This sounds a lot like a sovereign wealth fund. The government obtains fractional ownership over large enterprises (this can happen through market mechanisms or populist strongarming — choose your own adventure) and pours the profits on these investments into the social safety net or even citizens' dividends.

For this to work at scale domestically, the fund would need to be a double-digit percentage of the market cap of the entire US economy. It would be a pretty drastic departure from the way we do things now. There would be downsides: market distortions and fraud and capital flight.

But in my mind it would be a solution to the problem of wealth pooling up in the AI economy, and probably also a balm for the "pyramid scheme" aspect of Social Security which captures economic growth through payroll taxes (more people making more money, year on year) in a century where we expect the national population to peak and decline.

Pick your poison, I guess, but I want to see more discussion of this idea in the Overton window.
