If you remember half way into the doc they talk about how aggressive the recruiters are, targeting people that they know cant afford it, single moms, etc etc etc and selling them false dreams.
The reality is also that State schools are cutting back enrollment same with community colleges and as result U of Phoneix has a student body larger than all the UC's and Ivy leagues combined!!!
The interest on the loans they provided is insanely high, and call me what you want but I understood very little about finance when I was 18 n 19 and for many U of P and the other provide an advertised opportunity that many people would not be able to achieve through the normal channels of education, these types of institutions are getting more and more powerful, I forget the numbers, but they are spending more on marketing than a lot of major companies and they dont rely on donors they rely on investors...
