There is much wisdom here, grasshopper. Look at the opportunities out there for skilled tradesmen in this economy. I have advanced degrees in the arts. That, in retrospect, was just stupid from an economic standpoint. On the other hand, I wouldn't be the person I am without that education. Is a puzzlement.
If people get married, get employed, don't develop bad habits, and stay married, things are pretty likely to still work out though. For me, that's been the key. There is no substitute for a good marriage to make you happy and productive.
The best career development I've had was pursuing a 2nd bachelor's degree in a field to which I'm no longer employed and for which I still pay (nominal) student debt. Of course, within context I also made this decision as an adult/out of home, married, young-20s, so that probably weighs in my experience as well.
