In my review of Martin Scorsese's The Irishman I referenced Harvard Law Professor Jack Goldsmith's rebuttal of the film's storyline (based on Frank Sheeran's historically questionable late-life claims about his role in the murder of Jimmy Hoffa). In addition to debunking Sheeran's account, Goldsmith also argues that the film fails to address the more significant long-term consequences of, for example, how Robert Kennedy's vendetta against Hoffa helped undermine the position of organized labor more effectively than big business ever could, with consequences we are suffering from today. Certainly, one of the many differences between then (the 3rd quarter of the 20th century) and now is the powerful role played by organized labor in American society then as compared with its politically pitiful position now.
And now James Pinkerton at - of all places - The American Conservative, has joined the chorus with at least two-and-a-half cheers for the role of mid-20th-century labor unions, in a December 4 post entitled, 'The Irishman' Remembers when Unions gave Capitalism Its Ballast. https://www.theamericanconservative.com/articles/the-irishman-remembers-when-unions-gave-capitalism-its-ballast/
