Eastern Europe (EU). Yes, the cost of living is a lot higher in the US, but it's not 20×. Even if we compare it to any western euro country, we'll see that none of them have wages even close to US.

You are comparing apples to oranges here, how many European companies are as profitable as FAANG companies, when a company has more money and shortage of skilled people, salaries will rise to attract the best.
There are other factors like US workers work more and have other expenses since there is no welfare state while Europeans work less and also have a welfare state.
These numbers are pretty similar in NYC as compared to the country as a whole, too.
