I strongly disagree with pumping more money into universities. It seems so self evident that getting more graduates and spending more on higher education will power your economy, but the fact is there has never been a link between university spending and economic growth.
Universities work great when you have smart students dedicated to learning a subject in depth, and if you could just drive up student numbers and get more and more of those type of people it would be a fine strategy. But the more you push people to university, the less it becomes about knowledge. You just end up with certification factories, teaching average students nothing and conferring only a certificate that says "let me have a job".
Unfortunately, I don't think there is a way we can go back to a system where only a small minority got degrees and high school was enough for jobs so this is all a bit moot. Still, one thing I can say is that making university free for everyone will be a massive misallocation of funding.
