I think it's more like:
"For every[1] job J, there is a pay P such that if you're getting paid more than P, you'll more than like doing J."
[1] Actually, we have to exclude a lot of jobs from the set of possible jobs. There are many things I wouldn't do on a matter of personal principles, like designing bombs, for instance.
Edit: not that I agree with the thing, it is just my interpretation of it.
