Mayor Bloomberg advises middling high school students to go into a trade instead of college. His rationale is that unless you're a top student, you will get a better return from plumbing and working than four years of college, plus you'll be debt-free.
I'm on the fence, here, but I think he's generally correct. The decision is muddled by your major's prospects and made murkier still assuming college isn't strictly an economic decision. Some people, including yours truly, went because they didn't know what else to do. We all have our reasons, including avoiding trades because they aren't presTTTigious.
The decision is a lot less murky if you're pursuing a liberal arts degree and are thinking of doubling down and taking your 3.2/155 to law school. Just accept that everyone but you realizes it's a terrible idea, find something productive to do, and move on with your life. Especially if you're from Bergen County and attend Siena College.
