Higher education is only a quasi public good, it doesn't justify the same subsidy as K-12. Add to that and there's a very strong argument that since much of higher education is signaling (and not human capital formation), it's a waste of public funds.
Seconding the recommendation of Bryan Caplan (in particular this book of his) for hot takes, though his conclusion is more a reflection of his ideology than the underlying evidence.
A scattering of my own, though my hottest takes are reserved for K-12:
I'll stop there for now.
Evidence, to what end?
Ideology is about goals, not about process. Evidence helps point the way to achieve those goals. Evidence on its own gives you no goals to reach towards, and two ideologically opposed people, upon seeing and accepting the same evidence, will still draw divergent conclusions.
(For one funny example of this, you can look at Bryan Caplan and Freddie deBoer, an anarchocapitalist and a communist who both wrote books about education drawing from almost precisely the same body of evidence, only for one to conclude that the answer was to defund higher education while the other concluded we needed to support unions, increase funding across the board, and implement Medicare For All)
As for which side has the most evidence, mine does, of course.
