>somehow I ended up with a job that pays over $100K a year, that makes me work for about 3 hours a week from home and has been paying me for years to do that

That seems entirely consistent with the supply and demand explanation? If your employer thinks they're getting 100k worth of value from you, and that there's nobody that can do your job for cheaper, the fact that you wfh for 3hr/week doesn't affect the analysis.

>If I were to quit, I'd end up with another job that makes me work for 30+ hours a week, for the exact same salary.

That can partially be explained by the fact that labor is an illiquid market, caused by switching costs and lack of information. On the flip side, you might be able to get 500K working for MANGA if you grind leetcode/whiteboard prep.
