All modern Western-like societies involve some amount of indirect redistribution already. Outside of extremely peculiar places like Singapore or the Gulf states, it's just not seen as desirable or even sensible to have extreme wealth alongside people living in extreme poverty on the equivalent of less than a dollar a day. This actually used to be relatively common in the 19th century, it was the actual kind of widespread pathology that early social reformers railed against.
All that wealth people are bitchin about is ephemeral, its mostly unrealized gains on stocks that balloned.
People want to overtax Elon, but he doesn't sell his stocks. Its all imaginary numbers propped up by the federal reserve.
It is still extremely common today, if you look at the demographics along the Atlantic Coast of the US. The richest zip codes always have poor ones nearby.
By the standards of underdeveloped countries today or historical poverty in general, these "poor" people are nonetheless living in outright opulence: their genuine plight is mostly one of social marginalization, that can't really be solved by purely economic means. That's partly the effect of new technology (developed by capitalism) but partly redistribution in action.
