Over the last 50 years, your generic plastic army men (you know, these guys):
Have been stamped the following things, in this order:
Made in Japan
Made in Taiwan, ROC
Made in China
Made in Vietnam (I think that's the new locale)
The point being that jobs in factories that make cheap injection molded plastic toys are NOT first-world country jobs; they move as economies develop. We are never getting "cheap injection molded plastic toy jobs" back in the US....nor do we want them. Because the choice is either a shit job paying a sub-par wage, or a job in American conditions paying a good wage, in which case your $5 bag of plastic army men just became a $15-$20 bag of plastic army men.
Now, do the same for plastic car parts, electronic components, etc. etc. ad infinitum.
Americans DO NOT WANT THOSE JOBS. How do we know? Well we can look around at OTHER really hard, low-wage jobs: picking strawberries, installing roofs, working low-level construction jobs....and see that Americans don't want those jobs, either. That's why millions of hard working brown people are doing them. AND.....American consumers don't want to pay for goods, products, and services at the high prices that would follow such jobs paying the wage necessary to draw Americans. If you hated $7 eggs, you're REALLY gonna hate $8 lettuce, and $10 strawberries, and a new house that costs $300k instead of $240k.
You can bring back 90,000 cheap injection molded plastic toy factories.....not one job will result.
Or you can force the issue...and the factories will still close, because nobody is gonna buy the $20 bag of plastic army men.
Sure, there are some manufacturing opportunities and jobs that can and should exist in the US. And yes, globalization has left some people behind. But what is happening here is the elevation to god-like status of "mediocre white men." What, oh WHAT will we do with all of our mediocre white men? We yell at EVERYONE ELSE to "better themselves...learn to code!" and all that shit. But for mediocre white men? Nope, they should stay EXACTLY as they are, and we should just jump into a time machine to take us back to a time when 1) we had the the only major economy left standing after WWII, thus making us a manufacturing center, and 2) they didn't even have to compete for most of the decent manufacturing jobs because minorities and women largely need not apply.
The Trump administration is trying to turn back time. All that they'll accomplish is wrecking shit that will take decades to repair. Fucking idiots.
