We do not live in a society where people value human labor. Human labor is considered to be a cost center to be reduced or removed. I'm not advocating getting rid of human labor. What I am saying is huge gains in automation in every industry is reducing the need for labor. Very soon in the not too distant future factories and services will have 100% automation requiring no workers. Systems of production and service delivery will be scalable on demand without any need for workers. This is my point. The reason we have a super class is every year there becomes less of a reason to pay workers because workers are no longer needed or valued. This is a huge problem. What happens when we have self-driving trucks. At some point two parents working four jobs at fast food restaurants is simply not enough income to make the economy go.
I did not invent the point I was making. It's been something I've read in lots of places:
"Several OECD countries have been grappling not only with slow productivity growth but have additionally experienced a slowdown in real average wage growth relative to productivity growth, which has been reflected in a falling share of wages in GDP. At the same time, growth in low and middle wages has been lagging behind average wage growth, contributing to rising wage inequality. Together, these developments have resulted in the decoupling of growth in low and middle wages from growth in productivity."

If workers are NOT needed for production then we simply do not live in Karl's world of "Entfremdung".
