The reality is, most college grads are coming out with 5 or 6 figure student loan debt. Repayment starts within 6 months. You NEED to find a job to start repaying that. If you decide to go the full entrepreneurial route and end up missing even one payment, then you can go into immediate default and fines will be added, and your credit score will be impacted. If and when your entrepreneurial venture fizzles (as most do), you will have a tough time finding a job outside the startup community, because your low credit score and possible wage garnishment issues is a red flag to the pinheads in Human Resources.
This is reality, and I think kids in their 20's who go the startup route straight from college should be made aware of the risks.
