I'm sorry that this has been your experience, but I have to disagree.
An education is not something to regret. You may never have a career in your chosen field but you acquired knowledge you wouldn't have otherwise.
Your view of education seems very much like the WT's. "I'ts purpose is to find a job". Again, I disagree. Education is what rounds us out as humans. It opens our eyes. Expands our horizons.
Sounds like you would have been better off going to a trade school. And that's ok, I'm not knocking trade school. But for many of us, education means much more than a means to a good paycheck. :)
