Society rewards the idiot

How come society rewards the idiot? In today's society, the one who does the least important work almost always makes the most money. Lawyers, politicians, stock brokers etc. are rich, while cops, scientists and teachers are paid next to nothing.

Why the hell is this? What can be done? And why could most people care less?

I am >>5, therefore I run society

>>8, make me a a sandwich or I'll kill you!
