"to eliminate college tuition at in-state public colleges and universities for families with annual incomes under $125,000" And what happens if you make $126,000? Is it just gonna be a steep cliff where you go from no tuition to full price? Will this be conditioned to cost of living in the area? $125,000 in NYC and in Nebraska don't get you to the same place. I wish there was a solution between "free for all" and "repay your student loan for the next 25 years". Can we just figure out a plan to make it affordable without it being necessarily free?
