I will chime in and say a tech school degree is not the same as a 4 year degree; you're looking at a starting salary of maybe 30-40k as compared to 50-70k (depending highly on your field, but i'm thinking the engineering/manufacturing world)
Not all 4 year degrees are created equal, either... it's easier to get a job coming from a good school. However, that is a minor concern to many people. Just don't get a 4 year degree from a for-profit university (

However, a 4 year degree in liberal arts is pretty worthless. Get a degree with a very specific end career goal.
You can get to the same level as someone with a 4 year degree, but you have anywhere from a 5-10 year handicap on getting there (and in some cases longer or it doesn't happen)
I just finished my second 4-year degree and i'm planning a masters before too long. To me, the money spent on the (yes, fcuked up and overpriced) educational system is still worth a lot more than say, a brand new EVO X and always will be.
