What the college tuition debate overlooks is that for costs to go down, so does the quality of the experience. this means college is more barebones and less handholding, like in Europe.
Europe has a good approach by using subsidies as a more palatable UBI initiative to keep their startups afloat.
There's plenty of ways for Universities to lower costs without hurting quality.
There are plenty of open resources nowadays. Many of the paid online only textbooks with inconsistent tooling and accessibility for starters could be eliminated.
Expensive corporate software contracts is another. Access to MS office is nice in theory but in practice many students rely on Google instead AND there are open alternatives that don't have unreliable authentication problems.
The end result is that the average money received is about 60% (give or take 5-10 percent depending on left or right wing politics) of the institution rate so you now know the foreign "tax". If you are over 32 you should also pay the institution rate but it is almost fully tax deductible.
