I've taken a few classes in philosophy (it was my major for a while), and I can't tell if this is super different in the US vs Europe or you're just making stuff up, but this is just not what I saw. Yes, logic is part of philosophy, and everybody needs to take that class, but it's not heavily emphasized for the majority of students. Being able to write summaries and essays is, and learning the lingo, and reading (and hopefully understanding, or being able to pretend so well enough) the classics.

Please don't. Studying in the humanities doesn't make you a better person, and it doesn't make you consider ethics in everything you do either.
> School is the one place where we have an institutionalized system to study and progress the liberal arts as a whole
Except not everybody agrees that is what life is all about, what's best for society, the country, humanity or whatever you choose. Somebody has to do the actual work, you know? Sure, we can all become philosophers and then starve to death, or we can make sure that we have enough people that know how to grow food. When it comes down to it, yeah, with all of my ethics training, I very much prefer people that know how to grow food over people that will explain that the ethical thing to do is to feed them first, because only they can lead progress and advance the liberal arts. But then again, I always had a thing for utilitarianism and was highly suspicious of the bourgeois elitism in intellectual circles.
