This would save young Americans from going into crippling debt, but it would also make a university degree completely unaffordable for most. However, in the age of the Internet, that doesn’t mean they couldn’t get an education.
Consider the long term impact of this. There are a lot of different ways such a situation could go, for better and for worse.
A. That would only be true in a culture where employers don’t think you need a degree for basic jobs. From what I’ve seen, the US isn’t like that.
B. Even if people are practically able to turn down uni, all the universities will most likely agree to keep prices high, similar to what landlords do. If all of them keep their prices high, then all of them get more money.
If no one could get a degree, employers would have to change their requirements to reflect this. Otherwise they won’t be able to find any employees.
Universities need to have their classrooms filled to stay in business. If attendance plummets, then they will be forced to adapt by reducing tuition prices and reducing expenses, i.e. providing less amenities.
