Its not about the $ for the cult, People who go to college, will have their minds opened,They will have ideas that will conflict, and show the cult for what it is. Education is the light that shows the cult for what it is, and the cult can not stand with this kind of scrutiny.
Just like the church of scientology, they do not allow their people to even surf the net, with out the program they have developed installed on their members systems. the program blocks any site that is critical of their cult. The society does not have this type of software but does denture their members from using the internet. And tells them to run, if they start to see or hear anything that is critical of the the society.
The society would love their member to make more $, but they would rather have members that make 9k a year, than members that make 50k a year and move away from the cult. Or worse yet, start to tell others in the cult that the king has no clothes.
