I didn't read all of the replies, just some :)
However, I think some people are asking the wrong questions. In the context of finances, someone asking, 'should I go to college?' or 'Should I take out a loan to get some higher education?' are only NOT the right questions unless they are part of a larger plan. Are your parents wealthy and going to pay for it? Then go ahead if you like. Otherwise, take pause.
Two stories - I went to a moderately more expensive private school, worked hard (20-30hrs/wk) to avoid loans, but I had about $20k when I graduated (1 year early because I took some summer school and had a lot of 'free' credits from high school AP or whatever they call it). I found out there was a good market for IT during my junior year so I tacked on a CS minor. My degree has paid off well, I paid my loans back pretty quickly. My wife and I are debt free except for real estate. I make a comfortable salary well above the (US) average. We aren't wealthy (yet!), but she has the freedom to work or not.
Now, I have a friend who has a history degree. After a few years he went back to get a masters in education so he could teach. He had some unexpected circumstances that prevented him from finishing his student teaching, so still no masters. He has done everything under the sun - teaching (subbing mostly), sales, construction, etc. He has since gotten married and is starting a family. He's a great guy and has become proficient at most things construction related but he's worn out and wants to make a change but it's tough without much of a cushion. He'd like to start buying some rental properties, but that's out of the question right now. He's a couple years older, and I don't know if he had (or still has) student loans.
So was it worth it for me, for my friend? i'm not down on history or social work, etc. And if he had been able to finish up and enjoyed a career teaching history maybe it would look different. But, if you are going to 'invest' $20-50k/year into an education, please stop and think about the 'return' on that investment - unless you or your parents just have a couple hundred grand to toss at it, think about why you are studying and what it will gain you. Do you really want to buy an $80k BA in art or a $200k BA in history? Is that going to help you get where you want to go?
