Why compensation varies so much among countries?
Honest question: what is/are the reason(s) in your opinion why Google US pays much more than Google UK? Just an example of course.
Take Flipkart or Ola or any example where HQ is outside the US. A recent post mentioned top salary for Spotify was around USD 100k.
Naively I would expect that after taxes and cost of living every top company around the world would pay the same salary. But even inside the same company compensation net of tax vary widely.
