alt Hacker News> a company would rather hire 10 "market rate" people than 3 well-compensated ones
The former is probably easier. They don't have to justify or determine the salaries, and don't have to figure out who's worth the money, and don't have to figure out how to figure that out.
It also comes that the well-compensated people are probably that because they know how to advocate for their worth, which usually includes a list of things they will tolerate and a list they will not, whereas "market rate" is just happy to be there and more inclined to go along with, ya know, whatever.
