Higher education isn't just a personal investment. It's a public good that pays off in a more competitive workforce and better-informed and engaged citizens. Every year, we spend nearly $100 billion on corporate welfare, and more than $500 billion on defense spending. Surely ensuring the next generation can compete in the global economy is at least as important as subsidies for big business and military adventures around the globe. In fact, I think we can and must go further - not just making public higher education tuition-free, but reinventing education in America as we know it.
