Its crazy they dont even talk about this in American schools. They attribute it to Henry Ford.
Lived in a liberal state, but when I was in high school, they attributed it to the Wobblies and left it at that.
I mean, the Wobblies were a big part of the labor movement which achieved the 40-hour workweek. It’s just a mixture of “Glossing over” and “Complex background reduced to the most prominent actor regardless of whether it’s the right one”
