I'm sorry, what? What do you think 2023 mills, mines, and factories look like in the United States?
Here's a tour of a wheat mill: https://www.youtube.com/watch?v=PYP6AnNQjNo
Here's a modern coal mine: https://www.youtube.com/watch?v=Vwo3slH1wsk
And here's a modern factory: https://www.youtube.com/watch?v=mr9kK0_7x08
For example: the Natrona Heights steel mill now employs roughly 100 people on a shift vs when it employed somewhere between 5000-10000 on a shift. Automation killed a ton of employment. Those are the kind of jobs I am talking about.
Don't get me wrong. I don't want to bring all those jobs back. They were terrible jobs.
However, claiming that working those kinds of jobs somehow makes people better is quite suspect, at best.
I will say, I'm a 100% knowledge worker, and work from a laptop, but hard labor is good for you (within reason). We have all sorts of illnesses and obesity in modern society because our bodies were built for stamina that we no longer make use of.
I'm not sure I agree.
The work was hard and you didn't get anywhere.
You worked the farm, the mill, the mine, etc. just like your father did and his father did. You didn't get rich. You didn't even get comfortable. You were still poor, and your children were going to remain poor.
The window where labor unions made mill, mine, and factory jobs something livable was quite short--1960 to 1980, roughly.
Yeah, shitty, excruciating work was a good way to beat you kid over the head with "go find ANYTHING else to do as a career." Worked for my dad. Worked for Joe Namath's dad. etc.
Not sure I count that as anything "being lost" though.
