Nearly every Democrat — and likely a number of Republicans — running for statewide office this cycle will propose some sort of free college, debt-free college, or just general college affordability plan. Those plans need to be well-designed and in particular recognize the relationship between college affordability and college completion. Otherwise they’re apt at best to under deliver, and at worst, do more harm than good for a large number of students who end up dropping out with no degree and student loan debt for non-tuition and fee costs to boot.
