There is a very, very good chance that you will not come close to a return of investment for the better part of a decade and you will struggle to support your family without living paycheck to paycheck unless you have rich parents, your wife makes over $100k, get a second job that pays $60k, etc.

There is no movement, and nearly zero hiring, at all right now. If you do not have a degree, I would use that money to go to school and fly on the side to get you instructor ratings. After you finish, the industry might be better.
