Any data points for TCs in europe?

It's crap In NL there's just maybe Uber and Booking paying some half decent amount of money, you can search for threads, but it ain't much compared to US Best paying is probably Google Zurich, but it's still less than the US, at least gross TC

EU can never match US in TC. US can never match EU in public facilities.

If you want to use a proxy, look for income percentiles at different European countries. This data is publicly available. As a senior engineer at a top company I would expect your income anywhere between the top 5-2%. IMO you have to be very senior to break the top 1%, if ever.
