@raphjd And class-interest.
Left-wing academics produce nothing of value. So, how do they live? Off 1) public grants, 2) student payments.
To survive, left-wing academics MUST justify those payments ie. promote Credentialism & religion of their own superiority - and fake crises only they can solve eg. "Climate Change".
They MUST rate themselves highly & proclaim their own (phony) value - like @jaroonn does - because no one else will. No sane person would.
Their ideology, behavior, politics, pomposity & proclamations are........ .......... .....all to secure payments.
When USA Dollar & Empire crash in a hyperinflation disaster: countless left-wing academics will find out how little they contribute - how little people need them.
In German hyperinflation, they were suddenly out on street. Whereupon, as embittered authoritarians, they went Nazi.
