Time. You can be a hot shot lawyer making $500k a year and working 12 hours a day, or a software developer making $200k a year with a SaaS product working a few hours a day.
Also security. Imagine something happened and you got no income for the next 6 month. How big a deal would that be to you financially? is it "I would definitely default on my mortgage and lose my house" or "It would eat up a bit of my savings and perhaps I'll have to skip that one vacation I was planning"
Wealth is ultimately about outcome. On average more of my non-tech friends had to invest in education, work, housing and family because they didn't have a choice. Those things compounds just like money does. So now my non-tech friends, on average, have more going for them.
Don't get me wrong, I do absolutely have friend in tech that are doing exceedingly well both financially and personally. But mostly because they did something else that wasn't part of "the deal".
I mentioned my personal definition in a sibling comment. I say that being wealthy is a feeling, the feeling of abundance. You choose which things an abundance of makes you feel wealthy.
Who is really richer here?
