Creating jobs which don't do anything useful isn't productive.Education, humanitarian services and military are key. This would be an opportunity to move people in a better direction.
We need to open up higher education to everyone, free of charge. We need to revamp k - 12 education. There is no reason we can't train mass amounts of highly skilled people. Advanced degrees should no longer just be for the few. It should be normal for everyone to have a higher education and a specialty. Even if they never use it. This would also create many jobs in education.
But when the robots do nearly everything, perhaps we can afford hiring Sociology professors
to give people degrees in International Diversity Studies. (Yes, that's a real degree...Howard U.)
