You should be able to pay people just enough so they’ll work for you. That is how markets work. If some commodity doesn’t get bought for some price, there’s a reason.
Then, by the same token, people should work just enough so that they get paid. They shouldn't put more enthusiasm, care, and effort into their work than is necessary to obtain that paycheck. After all, that's how markets work.
[But that's not how I work.]

A while back I happened to hear a monologue by a Gulfstream-rich talk show host on the subject of employees.
Given his job and his lifestyle, he has a need for multiple employees. He said that, when he identifies a keeper, he makes sure the person is paid way more than he'd command in the normal market, and that that method has produced excellent results over time.
