Let's be honest, as European IT non managerial staff, that's enviable. Our pay normally caps at around 80k? 90k? Above that and you're probably in the 1%. Probably 10% are above 70k?
There's basically no purely technical path that gets you beyond 100k unless you're working for a foreign (probably UK or US) company. Maybe, maybe Swiss? You can't just keep getting technically better in your field (devops, qa, dev, architect, ML, data engineer, data analyst, ...) or multiple and make bank like these people do.

Managerial staff though... no limit in sight. I've seen managers piss away 200k on an incomplete homepage redesign because... no fucking idea, and they earned double my salary. I was dragged into meetings where managers revealed at every turn that they did not understand the people they were managing. It's understandable that they don't understand exactly what the engineers are doing, but not understanding the people is worse IMO.

You should be able to rely on your technical team to make technical decisions. IMO a manager's job is to give enough space for engineers to reach the best technical decision possible and deliver, while keeping them on track. But instead they keep organizing inane meetings with the sole outcome being another meeting with otherwise minimal action points. And the meetings are in the middle of the day.
Of course testing is not important to them (waste of time), documentation is not important (waste of time), deployment environments (expensive, no use), velocity in a sprint or sprint planning - you guessed it, waste of time.

Say what you will about Microsoft and big non-European companies, they may not care much about their employees as humans, but they pay them better.
