Even in the USA you're not getting to $5m net worth on salary alone, not without decades of it.

(Or as more likely, you've been in SV since Apple was a twinkle in the garage and your house is worth north of $5m.)

For comparison purposes, $5m invested well should be about $150k a year forever (3% safe withdrawal rate). If you have a net worth of $5m you should be able to live without working - if you want to (median US household income is $87k).

Anyway, off to buy some $10 bananas.
