When you consider how nearly half of working age adults are unemployed

Labor force participation rate is not the inverse of the unemployment rate. To support your position, you'd need to show dramatic reductions in labor force participation and show a causal link with automation. I am skeptical that you can.

And under-employment is not the same as employment.

Automation may not be solely responsible, it is one of many synergistic factors.
