You've probably already heard about Sen. Bernie Sanders' free-college tuition bill, which that promises a tuition-free education, so students can attend state colleges or universities with little cost. It sounds like a great idea, right? We'd no longer be able to complain about all the uneducated masses. Every student would have access to training to land them a career they'd love, without the burden of crushing student loan debt. Employers would have access to a more highly skilled pool of applicants. Eventually, even the economy as a whole could improve. So why isn't everyone on board?
