I agree with this, but not because I think automation is creating a dependent class, but rather automation is more generally freeing people from having to engage in low skilled labor in general. Once you have machines wholly producing food, structures and gadgets, the cost becomes so low as to be nearly free, and so universal basic income doesn't need to be that much money, either. Even now I see things on Amazon that cost so little, I wonder how they even justify selling making, selling and shipping it in the first place.
