So we've spent the last 40 some odd years automating everything we can get our hands on. We didn't automate meat cutters and burger flippers though. There's some people playing around with that but it's mostly for advanced robotics research. We focused on high paying jobs because of course we did.
So the guy doing mining making 100K a year got his job automated away and now he can go work at Walmart selling cheap crap made with the stuff pulled out of the mine.
The problem is that you're replacing 100K worth of income and economic activity with 30k.
This is why we have consistently seen the labor participation rate drop and this is why we keep having to cook the numbers on unemployment. This is why we have to pretend driving Uber is a full-time job and one the people are choosing instead of turning two out of desperation.
There's a concept called functional unemployment which is when you technically have a job but you can't support yourself on that job. I don't mean you can't support yourself well I mean you're working homeless or you are mooching off of family if you aren't somehow homeless. That's about 20% of our population.
Go to Google and search for the phrase "70% middle class job automation". You will find a study about that and about how automation has devastated the American middle class.
And here's the thing it didn't have to, but it did. That's a concept I think people have a hard time with especially people who dabble in progressive ideas or at least futurism. The idea of that well it didn't have to happen so it couldn't have happened. We could have created an economy where the benefits of that automation boom made it to everybody.. but we didn't. And we're not going to because every time you suggest doing that a bunch of old farts screams socialism in your ears.
