What is also missed is how much universities are dependent upon international graduate students because they pay the most. Then when those students demand GTA's the universities dream up new, costly classes, labs, and recitations, for no credit, which are not necessary to graduate, but are forced upon the undergraduates and go towards padding the GTA budget.
