"Not all children of bright parents are bright or motivated themselves. "
True. The latest estimates of IQ heritability are in the range of 70-80%. It is less than perfect 100%. Motivation is something the parents could [and should] instill, but no amount of motivation would ever suffice to make up for a serious lack of ability. Motivated ineptitude could carry a person only so far. I could turn myself inside out, and then back again, but I would never become an equal of Michelangelo, or even of a lesser luminary.

Only by some effete standards. My life is made better by knowing the names of good mechanics, carpenters, landscapers, etc. They may not be brilliant, but they are skilled.
And I wouldn't give a nickel for some of the PhD's I know.

I respect people who contribute to society, not ones who think they are superior.
