I should’ve specified, I live in America. I also did not live to see the 1970s in person, so my final paragraph should be taken with more salt than the preceding ones.
> Firstly you argue that "the right" is responsible for villifying government action, i.e. the population at large were basically static in their views until "the right" came along.
To be fair, “the right” is a fairly large section of the population. I don’t think it’s unfair to say that in general Americans are much more skeptical of the utility of government than they were 50 years ago.
I think your last paragraph is plausible, but it’s not my favored explanation.
For me, I think the decline in public opinion towards government programs started with racial integration. Around that time a surprisingly large chunk of white people appear to have willingly degraded their public institutions to avoid having to share with black people, sometimes going as far as literally filling recently integrated pools with concrete rather than share. You also see private Christian schools pop up with the explicit goal of being segregated.
Fun fact, organized evangelical involvement in right wing politics began with segregation. It’s only after the association with segregation became toxic did they pivot to abortion and homosexuality as their bête noire. They’ve tried their best to downplay this though, because it’s kind of an ugly truth.
Within this framework, the anti-government anti-public institution movement got rolling in the 1960s, and started to get a large political head by the 1970s and 1980s. The political turmoil within that period on the left in universities was a response and symptom of that anti-government swing, not a cause of it.
It is for certain possible that certain antics by academia during that time period came across as unpalatable to moderates, undermining their position. I just don’t think it was the cause.
