We really need to make high school diplomas mean something again. However, this means something like a 35% fail rate. Unfortunately, the populace would not accept that and so every credential gets inflated to worthlessness. 90%+ of all people in undergrad and 50% of grad school probably shouldn’t be there. They just want the credential, to get the job, to get the money. This is understandable but there is no interest…
The problem is that because you can no longer get a non-minimum wage job without a college degree, universities are now basically just a place to get a piece of paper so you can get a job, any job. They're no longer "halls of higher learning". A bachelor's degree is the new high school degree.
If you could earn a living without a college degree, like you used to be able to, those going to uni would be those who want to educate themselves.
