Your entire political statement aside manufacturing was always a good job. I’m not sure if you realize what kind of skilled labor went into manufacturing:
1. Machining 2. Tool and Die 3. Welding 4. Etc
Hell when I was working in construction I was making 20 dollars an hour at 18. That’s good money, and at the time if I would’ve stuck to it I would’ve been able to afford a decent life. My stint as a machinist while backbreaking at times was a good highly rewarding job.
Now, to address your political point. Yes, jobs should pay a living wage. Unfortunately even with such “wage suppression” America is still one of the most expensive countries to live in. We subsidize global food, drugs, etc. I can only agree with your point if we simultaneously become an export economy, and reduce or remove all global subsidy. But the party who supports raising wages also supports near limitless spending on the less fortunate countries. You cannot have both.
