However, I do generally agree with your diagnosis that the anger isn't so much about automation per se, as about changes in post-war economic structures finally starting to reach some tipping point, whether perceived rightly or not.
Wage growth for example has been flat overall:

Half of Americans make under 30k a year:

Yet the cost of goods has been increasing steadily:

I suppose the US's experience is not typical of the world's... after ww2, the US alone was something greater than 50% of global gdp, and its manufacturing base equally huge in comparison. Life is good when you are so far on top, even for the common worker, who with minimal education and no experience could find a job that supported an owned home, a homemaking wife, kids, a car, and two vacations a year. A couple of decades of that, and it starts to seem normal. But it was always abnormal, a result of fortunate post-war circumstances, and now that the rest of the world is catching up, perhaps we are returning to normality.
