To have a less stupid population.
What I support most is state colleges being free like K-12
K-12 is paid by local tax payers, who then fund their school district. You don't get to send your kids elsewhere though. Colleges would have to have a different model. Additionally, I'm not sure you can sell taxpayers on paying for ridiculous subjects and majors.
I could see myself being willing to pay for free engineering school (with certain performance stipulations, etc) or maybe a med school. But I'm not about to pay for liberal arts.
