And there is that. Lots of unique new problems. How does a worker compete with robot who requires neither wages, nor rest, nor sick leave, healthcare. Doesn't gripe about the workload, etc. etc.
Exactly, Dave! Honestly, the current assumptions are that, if nothing is done, unemployment even in America (to say nothing of Europe) will rise within 20 or so years to "levels not seen since the Great Depression".
Broadly speaking, there are two schemes currently being floated by people not blind to the most likely future. First, Guaranteed Universal Income. GUI is a move favored by many people. It would involve giving everyone a relatively small sum of money each month -- just enough to live on -- and perhaps paying for it by taxing robots (Bill Gate's proposal). People who wanted to work -- and could still find work -- could work, but people who either didn't want a job or couldn't find one would be taken care of.
The second is Guaranteed Work. GU would involve guaranteeing everyone a job on the order of what the Conservation Corps did during the great depression. That is, it would involve building schools, roads, etc.
Both plans have their strengths and weaknesses. But the "third plan" is the worse. Ignore the problem until 30% or more of the workers are unemployed and turning to crime and/or revolution to eat.
