The foundation of the neofeudal economy is this: the right of ownership still exists in name, but the actual ownership of political and financial power is concentrated in the hands of a few.
The core of American liberty is widespread private ownership of property. The Founding Fathers were quite clear on the necessity of protecting private ownership from encroachment by a covertly created monarchical Empire or a financial Aristocracy.
Private ownership protected liberty and the distribution of wealth by enabling widespread ownership of “the means of production” (land, tools, intellectual property, enterprises) and home ownership.
Thus the correlation between prosperity, widespread ownership of small businesses and homes and a relatively modest disparity of private wealth. When ownership of property becomes concentrated into a rentier class (i.e. a financial Aristocracy) that is protected by a Monocrat Central State, income disparity shoots up and prosperity is concentrated in the hands of the political and financial Elites.
In other words, the Founding Fathers understood that financial servitude precluded political liberty. Liberty in a neofeudal economy was ultimately liberty in name only.
