Hmm...
Well, only certain universities, that you pay to get into (or with scholarships) require you to have a stable balance. Which basically means that you have enough money for the general things you need in life. Only some universities actually are free and have a background that is meant for everyone. But unfortunately not all. However, if a student that wishes to get into a university without paying, he has to be uniquely brilliant. Which is why many universities let only a few students in without any charge. If he/she is not someone with the right knowledge, there would be no purpose. See my point? Hopefully this helps!
