Completely disagree. This is one of the biggest lies being forced by the higher castes in the US. "Smart" is subjective, "value" is subjective.
Let's be honest: this statement only true because a certain class of people want it to be true. I value k-12 education in my world view more than I value derivitaves traders: in my ideal world teaching would be a high-paying competitive field and Black-Scholes would mean absolutely nothing.
But I can't tell if you don't realize the world we live in is what me we make it, or if you just accept what you are told the world "should be" because you're benefiting from the system and are scared to make it equitable.
