Probably the top 5-6%. The numbers are lower but the behavior is similar. You’d be surprised how soon you hit the “More money than I know what to do with” line.
Make 150 to 200k/year (not uncommon on HN) and what are you gonna do, buy a new car every year? Rent is paid, food is paid, clothes are good, 1 or 2 vacations per year, go out to eat whenever you want, one-off nice purchases aren’t a big concern ... it’s cushy. Not enough to buy real estate cash or anything like that, but def more slosh than you need.
