Probably not a new idea, but something I've been wondering is if the US implemented progressive taxation, and instead of a UBI implemented a stock buyback program where the government buys shares and then redistributes ownership to citizens.

Even though this is totally wealth redistribution (which is politically unpopular, socialism and all), I bet you could market it as super American like Andrew Yang did with UBI as the "Freedom Dividend".

This way you could "work within the system" and still keep stonks going up, but also help redistribute wealth to poorer citizens.
