I rent out rooms in my house to two peers that are both college dropouts. Both work jobs that net less than $12/hour. I keep telling them to go to trade school but they never follow through. I got a 4 year degree, realized it was worthless (BFA in Digital Art), and proceeded to go to trade school for a certificate in manufacturing. Manufacturing sucks. For a hacker it is easy. I could quit today and be employed again by next week. The pay is good but not great. For someone votech was meant for, I don't think they have the same mobility as I do. Personally I keep looking to jump into development but I just haven't found the opportunity yet.
