Although I have yet to see a person with no lifestyle creep in these kinds of jobs. You start earning, you start spending. Yes, some people don't, but I keep hearing sad stories on that front too (guy did FIRE only for his wife to leave him after 6 months because they didn't keep up with the Kardashians. Some people feel mega-excluded if they can't partake in casual conversations like 'we are shopping for a new expensive carpet' or 'we just got a 8k lamp'.

I don't know if this is who you were talking about, but this guy was a big FIRE proponent/blogger who posted last year about his divorce after not updating his blog for several years: https://livingafi.com. It took a few years of early retirement and his coming down with a medical condition, though: "During this time of physical rehabilitation, while I was struggling with the physical issues, my partner finally figured out what would make her happier. It was a relationship with another man."

i would guess as a percentage there are two orders of magnitude more senior engineers at an arbitrary tech company vs managing directors at an arbitrary investment bank. senior engineer is ~5 years of experience to achieve, with maybe 1-2 years extra if you're meandering.

I was being facetious - advising someone to become rich and retire early by getting a very difficult to achieve role in another country 10x that counties annual salary in their 20s is not much better than saying to someone if they want to become rich they should just become a world famous actor or something. It’s just unrealistic advice that does more harm than good (and it rubs me the wrong way hence these responses lol). It seems to be a view perpetually shared by someone who knows someone who heard something and then treats it as the norm.

It is actually a lot better. The hard part is getting into the US, not getting one of these jobs. People meme about practicing leetcode for months but the reality is you should be able to land an offer with no more than 50-100 hours of practice (sure, you might need to do more if you're not actually that strong, but FAANG literally employees 5%+ of the engineers in the country, their standards aren't _that_ high).
