Yes, I'm from Spain and here a senior dev gets paid around 50-60k. That would be the salary for a junior dev or even an intern in the US.
As I junior dev I get paid 26k and it is considered quite high.
Depending on where you live rents can be higher or lower. In richer cities apartments might start at ~1200EUR, in other slightly more remote areas (everything is quite close together regardless..) 700EUR might be a more normal price. These are prices in the northwest of Europe, in Spain they are likely lower. In eastern Europe, much lower.
Most people in Europe with "normal", even though highly skilled jobs do not make large wads of money. Freelancing and consulting is where it's at (or Switzerland).
Intern salaries typically beat that in the SF at the larger companies, which is pretty wild by itself but is obviously just in line with the rest of the pay scale.
I live in the Bay Area and my home owners insurance (fires, earthquakes), property taxes, etc. are that much.
Very much looking to leave this area in 2022.
