I can't imagine hardly anyone goes to college for anything other than increasing their money making potential.
This makes me sad. Honestly. I know a lot of people feel this way, but to it expressed in such a blunt manner shows me how poor the educational system can be.
Many, many people go to college for reasons other than "increasing their money making potential", my wife being one. At my urging, she went (back) to college after we were married and got a B.A. in fine arts, graduating when she was nine months pregnant. She has not had a job or made any income in thirteen years, and we have no plans for her to do so. Despite this, her education was worth all the effort and every penny. She is more rounded, has more confidence and simply learned a great deal.
I really, really don't want to sound like I'm being rude, but the fact that you can't even imagine pursuing higher education for any reason other than money indicates to me that this is probably what was emphasized while you were in school.
Education can truly be its own reward.
