A quick google search says Ford assembly line worker salaries range from $20-38 an hour, with the typical wage of $28 per hour. It’s not a terrible salary, but I wouldn’t necessary say they they’re doing “very well”.
If we’re going off of OP’s math, the average autoworker only has a fifth of the purchasing power that autoworkers had in the 1960’s.
>”For decades, the UAW tugged wages upward. In 1960, a UAW member made 16 percent more than the average American manufacturing worker. By 2006, the figure was 74 percent. Today, new hires in the UAW make about 20 percent less than the average.”
