Since technology is infiltrating every aspect of our lives. When it comes to the stage where robots and automated machines will control all the production lines and any work force required in most occupations, including agriculture, labor and any service providing job (such as cashiers). Humans hopefully won't have to work as much , if at all. What would happen to most people.
I mean how would wealth be distributed, if you can have only a few people monitoring and fixing machines that can produce enough products to supply the masses, would the free market eradicate the unskilled untrained low IQ worker, since machines would be able to do any low skill job faster and more efficient than a human.
I know this is a far fetched 'sci-fi' scenario, but technology is heading in that direction, and I personally am with automating and creating a product at the lowest cost and as efficiently possible.
