I agree with that. I only mean that it’s not as simple as “if we gave everyone Elon’s money then we could all afford homes.” But you’re right, the higher concentration of wealth means there’s less investment into producing more resources that people need, so indirectly it does mean there are less homes to go around.

I do agree with what (I think) GP might have been trying to say though. Conspicuous spending itself is not a problem. Way rather have the ultra wealthy buying yachts that deciding to be a wealth-proportional amount of everyday commodities.
