The idea that workers were lording it over the rich from the 1930s through to the 1970s is preposterous. Unless the words political and control have been twisted to mean their polar opposites.
The post-WWII-but-pre-1970 economic world - the world of “embedded liberalism” - was a pleasant place. There were corporations, but they didn't do anything garish like compete with each other. Executive pay was taxed so heavily that nobody had much incentive to try to increase their profit margin; workforces were so heavily unionized that companies were nervous about any changes that might upset employees. As long as companies followed the script, the government embraced and protected them. Starting a new business was considered some bizarre act of alchemy, like discovering a new form of matter; normal people worked for the same giant company their whole life and got a nice gold watch as a reward when they retired. The government wasn't exactly socialist per se, but it kept starting and expanding programs like Medicare and Medicaid and Social Security, and every night you went to sleep knowing there would be probably be another uncontroversial, mostly-successful government welfare program tomorrow.
was it really so pleasant? inflation was very high, medical treatments were not so great, entertainment was expensive, most jobs still did not pay much, hours were long. Someone with a tech job probably earns more money on an inflation-adjusted basis and has a much nicer standard of living compared to someone living in the 60s
