You're two-thirds correct. While intelligence or acquired skills do generally
correlate well with material success, they are hardly a guarantee. There are
many stupid and incompetent people occupying highly-paid jobs, and there are
many competent and intelligent people who cannot find jobs.

If the correlation were complete, someone like Stephen Hawking, a respected
and competent scientist, would be making far more than someone like Carly
Fiorina, who was paid $45 million as reward for being fired and nearly driving
HP into bankruptcy.

Stupid people are
mostly unemployed, or do low paid menial work or are just
unemployable, and fortunately they dont fly planes.

There's a threshold of intelligence required to fly an airplane, but it's not
as high as many pilots like to believe.
