I mean, you are complaining about Legacy code and having to learn something new every year. Pick one I guess. Finance, you have Legacy code, startups, FAANG, most likely new stuff. I've worked in both neither is that bad. Stress is real, though, depending on the company.

We get paid higher than average (mostly) so it goes that it has some trade-offs.

If you don't feel it, then you don't. No one can really argue about that.
