The problem is that as a society we believe that people need to work 40 hours a week to survive. We replace people with robots and retain the same output. We are more productive than ever before, yet work the same amount. Physical and uneducated work is being replaced by automation, yet we expect these people replaced by robots to find jobs to survive where there are now none. I don't believe in Universal Basic Incom…
There are plenty of things people do that are valuable to society yet are not captured in the GDP, and are thus not highly valued by contemporary society. They range from visiting and looking after elder parents, playing with your children, writing poetry etc. Then there are undervalued activities which, due to being undervalued, are often rejected by people who would be good at them but can't afford a sacrifice (e.g. teaching, various kinds of social work, etc).
As the marginal cost of production asymptotes towards nil, peoples' sense of self worth from work (which is largely a modern belief anyway dating from the middle of the industrial revolution) can be sloughed off.
> I think the answer is that we need to move towards a shorter workday. Raise wages and shorten work hours.
I agree that we should do this urgently, but beware a belief in the "lump of labor fallacy".
Also, because people currently do develop a sense of self worth from their work, we should be investing heavily in helping people readjust to the loss of economic value in their work. For example governments offer retraining programs, but while a 20 year old coal miner may be able to find a job repairing trucks or writing reactive web apps, a 60 year old coal miner, who after two years of training becomes a 62 year old auto mechanic or web developer, will struggle to find employment. These people (both at 20 and 60) need assistance that also preserves their dignity.
