I do appreciate the sentiment in this article, but we do have to be careful. 'Capitalism" and "private enterprise" are not one and the same thing. Capitalism is mass production for sales in geographically extended markets. Private enterprise can be local production for local consumption. There is a place for both in this world, but justice does require addressing the economic power that the former generates.

That power is translated through money: money is the medium of economic power. Justice can be advanced by making some money (i.e., currency) independent of both the economic system and government. That is, its amount would not be influenced, much less controlled by any person, committee, or organization. Rather, it would be determined by demographics — and only that. That money would be used to fund (all) government and to pay an income to (eligible) citizens. If curious, there is "Same Economy, Way Better Outcomes for Society" (here in Medium). It is a model any nation could adopt.
