>I have no idea why American unions collapsed
I learnt a lot about that unknown history from Alex Carey's classic Taking the Risk Out of Democracy (1987). It was no accident but a huge and deliberate campaign. The story is pretty horrifying.

A small part of the story, from p31:
"The American Advertising Council represents large corporations and large advertising agencies. In April 1947 the council announced a $100 million advertising program which, over the next twelve months, would use all media 'to "sell" the American economic system' to the American people. The program was officially described as a 'major project of educating the American people about the economic facts of life'.
Daniel Bell, then an editor of Fortune, provides a perspective on both the scale and the anti-union and anti-New Deal purposes of these campaigns:
"It has been industry's prime concern, in the post war years, to change the climate of opinion ushered in by...the depression. This 'free enterprise' campaign has two essential aims: to re-win the loyalty of the worker which now goes to the union and to halt creeping socialism [i.e. the New Deal] ... In short the campaign has had the definite aim of seeking to shift the Democratic majority of the last 20 years into the Republican camp ..."
Bell sketches some of the resources, created to sell goods but now used in an overwhelming campaign to sell ideas. 'The apparatus itself is prodigious: 1,600 business periodicals, 577 commercial and financial digests, 2,500 advertising agencies, 500 public relations counsellors, 4,000 corporate public relations departments and more than 6,500 "house organs" with a combined circulation of more than 70 million. Of the opinion-shaping product Bell observes: "The output is staggering. The Advertising Council alone, in 1950, inspired 7 million lines of newspaper advertising stressing free enterprise, 400,000 car cards, 2,500,000,000 radio impressions ... By all odds it adds up to the most intensive "sales" campaign in the history of industry'
