Yes, there is. I just presented it with the TCO thing. What has been happening so far is that the displaced workers were offered jobs somewhere else because there was another need they could fill. The net drain does happen. It happens within the set of people working at a company, and the industry. Only if there is unmet demand in the overall economy does it not affect unemployment by having people do something else entirely - and I don't mean maintaining the machines, I already showed that to require fewer people.

The human labor per item still went down. You just threw a capacity expansion on top of the efficiency increase. That just means a competitor will be out of business soon meaning fewer people employed, not more.

It's full of product (all same model). Decades ago, prior to automation it was full of employee vehicles, and so was the overflow lot across the street to the west. The neighborhoods around there were thriving and now are quire run down.

We've been lucky in finding new things for people to do outside of industries where this happens. People can only consume so much in a day though, and as the labor hours required to fill human-need-hours goes down there will be a problem.
