It is a way to such money in to the system and burden the younger generations with debt they cannot bankrupt out of.
It is strange for me that these so called universities claim that if you get a degree from them you are guaranteed to get a good/handsome job in the market and when people like you tell them it is a "Ponzi Scheme" these universities will tell you that they have a system called "Alumni" which is a group of those students that have completed their degrees and they will help each other out getting a job meaning networking. But I have seen high ranked University graduates that go to LinkedIn and end up becoming full time freelancers instead so the hard work, time and money that they spent getting a degree is all lost somehow cause in the job market you require an "Approach" from some one big.
