That is the top performer salary, if any. When I check glassdoor for software engineer salaries at Amazon; average base salary is around 128K$ and top is 225K$ among all disclosed on glassdoor.

That being said, I don't know if I would plan my life entirely around being in the absolute top %10 of engineers. Avg. seems like a better figure to compare when speaking of whole markets/countries.

I plan to be at top %40 of engineers in a given field as a specialist and be a generalist overall. Seems like EU is a better fit for me then.
