You are incorrect about the Student Aid and Pell Grant programs since this was specifically addressed by Paul in his proposal.
So I agree with all your sentiment about the productive and beneficial uses of education in society. What I don't agree with is the notion that somehow a federal bureaucracy infrastructure has anything to do with the education of my children other than interference.

The government can subsidize housing against what the market can bear and build up an artificial bubble that even the government cannot prevent from imploding.
Or it can subsidize insurance with FEMA and completely destroy the concept of risk assessment by guaranteeing properties that have no business being build on flood plains.
Or it can build levy after levy in direct opposition to mother nature only to have mother nature kick its butt.
By propping up companies and ideas that are unsustainable in the market through cronyism, lobbyists, and campaign contributions you simply create yet another bubble that nature wants to pop. It is no use priming the pump when no one is thirsty.
