A job is not just a job to most people. It's their livelihood and purpose in life. It's very cruel to deny someone their an opportunity to be independent of the state
I don't know what work people will be doing when technology replaces everyone's work.
It's also true that were I around in 1880 I would not know what roughly half of the US population who were then farmers would be doing after automation.
For those new-age luddites who are generally afraid of technology destroying jobs, why stop at tomorrow's technologies? Why not outlaw washing machines? Surely elimination of washing machines would bring back a lot of jobs. Or let's outlaw productivity tools like spreadsheets. If people were forced to do everything by hand, surely this would create a lot of jobs.
Would you propose we eliminate any of today's technology? Why is it always that today's technologies are OK but not tomorrow's? Those will surely be our downfall.
Ironically, increasing the cost of human capital through a minimum wage will surely hasten the replacement of human capital by machines.
