Here's part of an amazing commenton the college issue:

My point is that no kid is inherently, at birth, destined to be a mechanic, a lawyer, a businessman, the President of the United States. The preferences for professions are developed over years of influence by the kid’s parents, schools, family, friends, and overall environment. Assuming that certain kids “should” pursue one path over another is validating the accumulation of privileged differences over childhood. I can see someone somewhere saying “It’s not that Mexicans aren’t smart enough to go to college; it’s that they want to be mechanics.”
