Take it one farther: how many people are willing to do numerical analysis for any amount of money? What concrete benefit does a company reap for having this analysis done? Basically, divide benefit by supply to arrive at the salary.
That's why the average salary for programmers ballooned (companies realized the huge benefits) then sank (clueless trade-school graduates crashed the party).
Replying to the grandparent, if your culture (whereever you are) truly values great children's theater, you should have no trouble paying for it. e.g. every cathedral ever built. Don't bitch, donate or raise funds!
