I don't understand this sentiment. I didn't go to university to learn "how broad knowledge is". Haven't you had 11 years of school to learn this? Haven't you had 18 years of formative relations with your parents to learn this? Learning this at college sounds like a massive waste of (1) money (2) your time (3) time of professors.

The US spends ~3.5% of GDP on non-tertiary education and ~2.5% on tertiary education. If what you are saying is representative of the general population, it means there is a massive unjustified waste of resources.
