I am not sure this is the right way of looking at it. Maybe they are quite happy and care about what they do rather than considering themselves stuck in a groove?Take Asia for example, there are billions of small business men, selling baskets and foods on the street, but they remain stuck in that groove.
Some people don't push toward the idea of creating more and more just for the sake of it.
I always like to think about the story Bill Gates told about the fisherman in the West Indies. He had a big mansion next to some old guys shack. Bill Gates watched him go out everyday and catch some fish for dinner and then go to market to sell the excess. Bill asked him why he didn't catch more and save to buy a bigger boat and hire crew to fish for him, and then expand into a fleet. He simply said, if I did that and made millions like you then I would buy a nice house on this beautiful beach and spend my days enjoying it with my wife.
He already had his dream. He was simply did not have the drive or want to build some fishing empire. People are different, and some may dream about having this or that, but when it comes down to it a lot of the time if we look hard enough at ourselves we know what we're capable of and know what excuses we make for ourselves for not being who we really are.
Point being Socrat, you may have the business mind and drive to create a basket weaving empire and dream of all the good you could do by providing jobs, or maybe you just want a nicer car and a bigger house, but that is not everyone's dream and even if the dream is achieved it is a pitiful goal.
In a more serious tone, I do think there is a risk of creating a workforce that is forever hovering around the poverty line. For some I can see the stress would be horrible and would not wish such constant pressure on anyone. At least if people can eat and have enough basic nutrition their brains are functioning well enough to create a path out of the situation if they are under duress.
The whoel IQ issue is a looming problem too and one ignored. With 10% of the population of around IQ levels of 85 and below there simply are not enough jobs to go around. They are capable only of simple manual labour. Given that those jobs are being taken away even more people are left with nothing to do and no doubt feel quite cold shouldered by society.
It appears mas industry is moving more toward creativity and artistic endeavors. This will hopefully at least provide some in the lower regions of IQ to rise up into social industry because artistic ability seems to be mostly unrelated to IQ. Th eproblem is then one of exploitation.
