Poor people get scholarships, get dismissed from university cost even.
And aside from wealth, everyone can repeatedly enroll in classes for many years (although if you don't pass you have to payback what was given to you) and waste everyone's ressources for useless, unfinished degrees (hello first year of sociology or other bullshit).
It is not like it was a vacation. In most cases, you still have to pay a rent, food, etc ...
And you commit several years of your life to it, that's the most precious resource you can give.
I can't believe I am discussing this to be honest, that's an insane argument.
