so, let's just say that theoretically there came to be one of those unicorn morale billionaires. someone who came from nothing but eventually came to learn how this whole fucked system came about, then exploited it themselves to grab as much $ as they can (ie. just yoinked $ from the stock market during a crash...about as morale as making $ you didnt work for gets) but they didn't let it corrupt them nor get distracted by the bread & circus.

an actual proper robinhood type, that just has effectively infinite $ to throw into the Great Game, how would this person go about affecting as much pro-labor change in the ol' USA?

to me, the most impactful area appears to be media control. murdoch as his fingers in damn near everything, the propagandas grip undeniable once you finally become aware of it. various other far right/lib billionaires either outright own or otherwise heavily influence damn near every media company, to include NPR. the only mainstream outlet that even remotely acknowledges/covers the genocide in palestine (though still refuses to call it a genocide) is AP news.
