Yes, college is worth the cost because of several reasons:
1.) It is very hard to get any kind of job without a bachelor's degree. Unless you want to go into the military, be a plumber or electrician (both well paying), or be stuck working construction or other types of strenuous, low-paying jobs, you need a degree.
2.) You meet tons of people and are exposed to all different kinds of people and ideas that you would probably not be exposed to. If anything, it makes you question and/or reinforce your beliefs that you came in with. Also, you meet tons of great friends and have wild weekend parties.
3.) You get to be part of a small group in American society that posses a completion of higher education.
So yes, if you can afford it, college is very much worth it.
Edit: Also, getting a communications, philosophy, psych (with no plans of grad school), or English literature degrees would simply be wasting your time unless you plan on getting a Ph.D and becoming a professor.
