You should pay for how much is being contributed.

Well, this simply isn't how it works in capitalism. Garbage truck workers also contribute a lot to society (wait until they go on strike for a month). However, the job is paid badly, since it requires very little education, so almost anyone can do the job.

If you actually take the word "contribute" to a better degree, if a work can be done by anyone even though the society needs it, it's not much of a contribution.
