Right now, the unemployment plus underemployment rate for recent college graduates is 53%. Quite a bit higher than the national unemployment rate. $100-200k in student loans (which will cost closer to $300-400k to pay off with interest) doesn't make it easy to get by even if you landed a great job. A low-paying, risky startup job might not even be a realistic option once you're saddled with debt.
This is the time to think about things like that -- what you can afford, how you'll repay it, what kind of job you want when you get out, where you want to work, whether the name recognition of an ivy league school matters to those companies (and whether that's worth as much money as a small house versus going somewhere cheaper), etc.
