The educational system in the US was a highly predictable victim of the neoliberal reaction, guided by the maxim of "private affluence and public squalor."

Cost-cutting leads to hyper-exploitation of the more vulnerable, creating a new precariat of graduate students and adjuncts surviving on a bare pittance, replacing tenured faculty.
