> I'd never met anyone taking about buying a house in the Spanish hills until becoming a techie.

I'm still not sure that's the differentiating factor here. OP made clear their moral objections, and sketched out part of a picture in which what makes this possible is not so much "typical tech money", but possibly "having owned a home in the US for long enough".

I have extremely non-tech but upper-middle class friends who in the past have discussed buying entire villages in Spain and Italy (they can be had for as little as $2-300k on the low end. These are not people who ever made "a lot of money", but they have owned homes for long enough that if they sold their house, they'd have capital to put into such a move.
