Student load debt is a big problem. But, it isn't that big of a deal. It has an easy solution too - stop taking on debt for education. Or, if you really must do so, make sure its management. Go to community college, go part time, or whatever. Don't borrow more than $6-7k per year, and you'll have manageable debt when you get out.
