A lot of us aren't gonna leave 5x the wage on the table.
All the interviews at Google are 45 minutes, and when I interviewed only 2 had coding, so there was realistically 70-80 minutes of coding that day. I did maybe 15 minutes in a phone screen on an earlier date. Even if you did only 60 minutes for the whole process, you really aren't that far off from a typical FAANG.
Could I use more money? Probably. But would I be happier with more? The research suggests I wouldn't.
I think for most people amounts up to something like 200-500k/yr (depending on COL) would provide increased happiness. Basically, if you ever have to worry about not having enough money, you could stand to make more.
Of course that doesn't mean it's necessarily worthwhile to work more to achieve that, that would be a personal decision you have to make yourself.
I already make a 90th percentile income for my area, and I don't feel that investing additional mental and emotional resources in maximizing salary is the best route forward for pursuing happiness. I think that at this point there are other axes to optimize on that provide greater marginal gains to happiness.
