"During this time automation of jobs has been occurring in other industries, and less new jobs have appeared than have gone."
I would somewhat agree but if that wrong? Disabled people and children used to work from a young age and now they dont, with children particularly freed up for education.
However since 90% of the population used to work in farming and agriculture and we have <5% unemployment accepting the welfare state as a product of our (countries) success/wealth it would seem the jobs have been replaced. Add the product of immigration and the jobs havnt just been replaced but far more have been created.
