It’s typical tech salary for people with ~5+ years of experience doing something interesting.
Sometimes reading HN gives me the feeling that there is no "tech" other than FAANG in the US. Or somehow every little "tech" company is just making FU money, which sounds hard to believe.
For reference, in my G7 country $5k are 3 to 4 months wage.
This is a case of "get deep knowledge about something which can not be replicated by googling your way out". Become a recognized expert in compilers, OS internals, or similar areas and suddenly you get $250-300k anywhere in US/Canada. Europe tech salaries are much lower.
