The mistake you're making is in thinking there is some objective definition of "value" - as in, there is some all-seeing entity which knows everything and knows exactly what a person "should" be paid.

I would argue that that's a fundamentally incorrect way of looking at it. You're "worth" whatever you can negotiate for (making baseline assumptions about not defrauding people).

If you can convince someone to pay you 10 million dollars to mow his lawn, I think you deserve every penny.
