Luckily all the high-school dropouts flipping burgers can just go to college and get a degree in liberal arts. Problem solved! They've lived so frugally over the years they surely must have enough money saved up to pay for that plus kids/rent while unemployed.
Oh wait, no, maybe the solution is raising minimum wage? Oh, that'll accelerate automation you say? Hmm.
Institutional unemployment is best paid for institutionally (free education) or else the problems will be paid institutionally anyway (crime, poverty, social welfare programs.) I knew someone who never went to high school because her broke parents were too poor to afford the $50/year fee; if that fee were waived, that $200 would've paid for itself many times over in reduced social welfare costs.
As an increasing number of people are shuffled into a decreasing number of jobs, it'll lead to wage depression. Higher productivity will lower costs of goods and services to offset this somewhat, but lowered job security and making more people unemployable is a more serious price paid. The only winners here are those who own the means of production. Publicly available replicators or central planning are potential solutions. Nationalized real estate + basic income could work as well.
