There are few growth stocks, so I'd expect compensation figures are not strongly skewed by stock bonuses, and are a function of market and fiscal environments much more than profit. When they are raking it in, it will be mostly going to US investors' pockets via buybacks.

Mind you, there are exceptions. The CEO of a certain hotel bookings company makes €17M/year. Technically an american company though.

They don't by and large. Listing the top 50 tech companies in the world by revenue will show that the US dominates it.

The few that appear on the list pay FAANG-level salaries for the most part.

Probably this I only know Finland tech scene but eg lot of Nokia engineers did FAANG like salaries in 2000s and there is now couple unicorns here where senior employees do very well.

Nokia valued managers, but not engineers. Good engineers became not so good managers to get a raise. We know how the story ended.

From world market leader to out of business in 7 years.
