Humans are rational creatures and will decide to work. Right now the pendulum swings too far towards welfare reliance in many areas.
The only solution is for the able to pay others to not work, through welfare. The improvements in technology should more than make up for this loss.
The owners of the tech is highly likely to prefer to capture fully the output (by lowering taxes for example).
I think there should be a way to align incentives - education paid for by owners of the tech, but also a contractual obligation to work for X years for their sponsors.
If the point is that those people produce no value, they shouldn't work at all. They could just dig and fill ditches, but that doesn't produce value. Amazon also leeches from the public goods, but that is somehow socially acceptable.
The NYC school system has the "rubber room", where unflushable employees are warehoused.
One of the reasons I support UBI is because it's cheaper than welfare for keeping certain people out of the way.
> Humans are rational creatures
I think this claim needs to be backed up too. There is a lot of evidence indicating that we're incredibly irrational.
