I have always found it is the people who are clueless about how the economies work who are concerned with automation.

first look at Germany. they have one of the more advanced labor markets from my perspective. they produce so much and consume so little their prices have been falling, what does the government do, oh that's right they print money. you get paid to borrow money! they had negative interest rates.(they were not negative enough to see negative consumer rates but it would happen) imagine your bank paying you to take a mortgage and buy a house!

then in america we have disability, if you are un able to find meaningful work due to some disability then you get money to spend without having to work. we have seen this is causing the disabled population to have the highest un employment rate in years. so before we worry about what the average person will do lets get all the disabled people to stop working.

then in minnesota when the iron workers lost their jobs due to the closing of an iron mine. we extended unemployment to them for a few more months if not 6+ months, where they could if they wanted to get re educated and find some more work to do. if we had to we probably would have extended it much longer.

we already have food stamps section 8, general assistance, medical assistance. I was able to live for 6 months touching no more than 20 dollars.

there also is deflation. if the robots produce everything then it will not have any production cost. and prices could be pennies. so if you earn 15 dollars you could feed a family of 6000 for a few weeks per hour of work.

tl:dr; anyone who understand the economy knows we will handle this transition nicely and probably not even notice it occurring.
