While I agree with the points you make, there are no easy answers here. The problem with technology concentrating wealth in the hands of fewer and fewer people is that it gets really hard to tax those individuals. Partly because these people can move around easily and avoid your taxes, partly because it becomes morally difficult when the amount you're taking off one person is literally 100,000x what you're taking off someone else but also because, unlike the middle classes, the sums involved make it worth those individuals' time to hack the tax system to avoid taxes. Companies at least have offices or retail outlets that are stuck in your territory and can be inspected by tax inspectors and have turnover that cannot be disputed. So successfully getting at the proportion of GDP that the government needs to be able to give everyone a basic income may well be easier if you go after companies.
