Well there's your problem. Extremely few well paying (say $150k+) jobs and crazy taxes don't exactly encourage wealth accumulation.

Try Bay Area - with tech salaries there and stocks growth being what they were this past decade, the real question is how is it not possible (if only you wanted) to have made $2M+ working for a FAANG for a decade there.

Or at least go for Switzerland, although market is much smaller there, beware. But I know multiple multimillionares in person who made it all on Google Zurich payroll.
