This makes sense, if there is some sort of government sponsorship or grants, but providing these to all people would mean drastically higher taxes, and companies are opposed to those.
I think the funding issue can be figured out without higher taxes or at the very least without absurdly higher taxes. Perhaps one idea would be to train people to invest through grades 9-12, have some sort of basic minimum income which isn't rich but isn't below poverty either; encourage people to invest with those funds and use profits to pay for college etc. I also sort of align with Jaron Lanier's concept of paying people for their data usage; but built onto that maybe so that it includes both government and private companies usage of that data; individuals don't see those funds until 18, from which they are encourage to go to school. As those funds are held they are invested like social security maybe? None of these ideas are really all that worked out just yet, just responding to you is all.
