Of course it is. It has delivered, flawed as it is. Please understand that. Otherwise i have two concerns.
The first is that it needs to be accelerated by ending global poverty which will serve to strip out core imbalances. We need as much more of all this as we can get.
The second it that we have power elites everywhere attempting to establish rents through secret dealings and that is generally unacceptable. Best practice tells me that all such advantages need to be phased out at a fixed rate of five to ten percent per year. The whole idea is contrary to free tradethinking and the natural advantages that brings. Yet free trade also needs to be carefully managed by restricting access under a stake holders cartel or capital will be used to suppress valid competition. We really do not want want egg dumping and we also are prepared to pay for quality local production that leads to environmentally sustainable operations as well.
The imbalances decried by excessive capital accumulation is meaningless if that capital cannot be used to produce wealth. Our own world sees individuals earning a base of approximately $15,000 through an optimal $150,000. That obviously works out to be around ten times the base. Income after all that means spending on personal use capital assets which acts to actually divert the individuals attention. And who really cares if some fool owns a giant yacht so long as a bunch of folks built it for him and patted him on the ass on the way through the showroom?
Those are then non earning assets having no economic value. ..
