Some countries do in fact do this by making post-secondary education free. But the key problem is the artificial requirements imposed by employers to people to have degrees to do jobs that in no way require them. Instead a degree is used as a proxy metric, and like Betterbridge keeps hammering at us, it stops being a good one once the everyone abuses it.
If we need to meet in the middle for now and only make all degrees required for jobs free I would be willing to do that, but I also won’t deny the obvious societal benefits to having a collection of people educated in the liberal arts.
I'll go ahead and deny the benefits of widespread tertiary liberal arts education. I honestly don't see it working; if anything modern "liberal arts" seem to be undermining liberalism. Certainly it's not obviously beneficial.
I do also think we need to reduce degree requirements. e.g. it should not require a university degree to teach elementary school. If we actually allowed people to fail high school, then a diploma would more than suffice. Likely the same for most "any degree required" type of jobs. Then we should have merit scholarships for things that actually require the additional education. Engineers and doctors should not have to pay for their degrees, but it should be hard to get them, and most people will not be capable. That's fine; you want very competent people there.
Some credentials could also be granted purely through tests again. e.g. my mom self-studied for her CPA. Now you can't do that. There's absolutely no reason you should need school for that.
