What a lot of people don't seem to get is that if a substantial fraction of labor gets displaced, market forces will tend to devalue *all* labor.
Yes, maybe *my* job is safe, but my pay doesn't have to stay high.
Suppose all truck drivers are replaced with automation. That's 1M more people on the job market. Yes, maybe they can't do MY job, but, with no alternative, they'll try to get educated and move up the labor food chain.
And with more people in general chasing ever fewer jobs, there'll always be someone willing to do any given job for cheaper--including mine.
Arguably this has already happened significantly. Do you realize that the share of corporate productivity that goes to labor has shrunk in half compared to 1973?
That if labor got the same share of productivity today that it had in 1973, that we'd all have 2x the purchasing power? I'd love to be paid 2x the purchasing power. I'd be done with my mortgage, be completely unworried about retirement and paying for medical care, etc.
I welcome automation replacing labor, but we have to find a way to distribute the resulting wealth such that the people who own things have don't have ALL the wealth and so that the people who can no longer make ends meet in a depressed labor market can live decent lives.
