I suspect most likely that more Nazis came to America. I was a student at Harvard during the early 1950s. There was practically no Jewish faculty there.
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." Funding for public education has sharply declined. As higher education is driven to a business model in accord with neoliberal doctrine, administrative bureaucracy has sharply increased at the expense of faculty and students. 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.
Education is really aimed at helping students get to the point where they can learn on their own. . .
Students typically are at a period of their lives when they're more free than at any other time. They're out of parental control. They're not yet burdened by the needs of trying to put food on the table in a pretty repressive environment, often, and they're free to explore, to create, to invent, to act, and to organize. Over and over through the years, student activism has been extremely significant in initiating and galvanizing major changes. I don't see any reason for that to change.
They, students have a degree of freedom that nobody else has.
