I wonder if this is why American students are much more reluctant to pick STEM degrees than other equivalent countries? Like, they can't handle any setbacks hurting their self-esteem so they pick a simpler major instead of pushing through. Like, "I didn't really fail that calculus class, I just didn't want to study it so I choose a business major instead!".
