Is a 4 year education and a degree valuable? Of course.
Is it worth $xx,000 in student debt and 4 year opportunity cost of doing something else? Rarely. Especially for this crowd.
If you are a 19 year old with some programming skills, and you are paying for your own college (via loans or with cash) dropping out is a GREAT idea. Spend the next three years working on your own projects, open source projects, crappy little free lance whatever.. you are going to be in a much better spot than if you spent the next three years going to classes and coming out with 50k in student loan debt.
If college is free, then yeah, you are crazy not to go. But if you are smart and willing to work hard anyway.. education is FREE these days. Save the cost of the house and the years.
