You have a point – however, do you know what SWEs in the big US cities earn theses days, working for “FAANG”? (Or Stripe, Square, etc.) It’s not very uncommon to have a yearly compensation of 500-600k or more (USD).
In Sweden, very very few SWEs earn more than 80k/year.
I don’t know if we agree on what the definition of massively rich is. Given that 1% of US people are millionaires, my definition of massively rich is 50MM plus net worth.
In Sweden, very very few SWEs earn more than 80k/year.
