For my $0.02, I would say, go to state school. Private college tuition has been increasing out of all proportion, due mainly to the readily available student loan. I agree that borrowing for your education is probably a good investment, but not borrowing the increasingly exorbitant amounts required for private school.
For what it's worth, I went to both private college and law school, received the advice to consider state school, and blew it off.
I was an English and philosophy major, as well, and there is virtually no ROI on that action. The end result: it took me a long time to dig out of the hole I didn't need to put myself in.
The absolute best advice I can think of on the subject though, is to follow one of Stephen Covey's habits: begin with the end in mind. Don't think about college as the end in and of itself. Think about where you want to go, what you want to achieve in the medium to long term, and then make the best college choice you can to help you get there.
Good luck!
