But "smartness" is completely relative to the field that you are in. If a student is good at and enjoys playing the piano, and chooses to pursue that path, of course they're not going to be as good at mathematics. That doesn't mean they're not a fantastical piano player. You're judging a fish by it's ability to climb a tree. Saying my argument is just "feelings" isn't it at all.

I am NOT saying that they all "fell" into it.

But you literally were saying this just a few posts ago. Your exact words were:

I am the kind of people that thinks people who took liberal arts degrees would have ideally loved to go into a more hard skill course and just couldn't cut it

Yes, the average student from each path is different from each other. But that is not the same as, they aren't smart enough to do it. Chances are you wouldn't cut it at a conservatory playing piano. Does that mean you aren't smart enough to do it? Of course not, it's just something you don't want to pursue.

You're right, I don't know everything about the caste system, but I do know some fucked up shit happened because of it. I won't pretend to know everything, I'm sure it's more complex socially and economically, just like the US electing "Mr. Orange" as you pointed out. The point I was making with that is, a person is not lesser based on their profession or socioeconomic status.
