Should the federal government pay for tuition at four-year colleges and universities?

A 2017 College Board study estimated that the cost of college has increased 100% since 2001. The St. Louis Federal Reserve Bank estimates that U.S. college tuition debt has increased from $480 billion in 2006 to $1.5 trillion in 2018. Several 2020 Democratic Presidential Primary candidates have argued that the cost of college is out of control and that the government should pay for tuition. Opponents argue that the government cant afford it and point to estimates from the Committee for a Responsible Federal budget that estimate programs would cost the government $80 billion a year.
