If you can't afford a nice house with 350k/year, move a mile or two away from your upper class enclave to the middle class neighborhood and live like a king.
People really do think of themselves as at the top when they're not. You're very good but not the top.

Look up housing prices in some major European cities (generally way less affordable that in most of the US if adjusted by income).
In London, Paris or Munich prices are about as bad as in SF or NY yet median income is considerably lower (also good luck getting a fixed 30 year mortgage, so there is also considerably more risk even if you can afford it)
> suddenly become poor
If you earn over €350k per year you really have to make some very poor financial decisions for that to happen. Besides from changing illnesses/accidents etc. but you would still most likely end up in a much better position financially if you saved that extra 10% you pay in taxes or went with a private insurance option.
Of course healthcare is probably a different matter.
> $350k… extremely wealthy
In many parts of California this is someone who can buy a just okay house with a long mortgage. Have we redefined the word wealthy?
