If you're getting a necessary degree, it's very uncommon to default on your loan because you'll be in demand and getting a decent wage. Banks understand this fact and will do the math to give a loan anyway.
Some of my kids seem like they enjoy academics, but others do not. I'll be pushing the latter toward trade school. Average IBEW (electrical union) pay is about $20/hr for an apprentice and $33 for a journeyman. $40,000 to $66,000 with ZERO DEBT right out the gate is nothing to ignore (and that pay can easily double -- especially in your younger years -- if you're willing to travel and put in those extra hours). It sure beats minimum wage at a crappy service job.
