The Catholic theory of property as summarized in CCC 2402 or as attributed to the natural law by Thomas states that the principle of all property is the universal destination of all goods, which states that all things first belong by right to all persons. The right to private property arises downstream from this, as a result of an attempt to preserve the very common good of the society that is prior to private ownership. Starting at least with Hobbes, the order of property reverses: ownership is fundamentally private ownership, and social goods only arise after we divest ourselves of property rights by handing them over to the sovereign.
Both the Catholic and the Hobbesian theory involve a sort of exitus-reditus, since both take the source of property as what must be preserved by the what arises at the later stage. Catholicism sees property as fundamentally communal and the purpose of the subsequent system of private ownership as the preservation of property’s fundamentally common character; Hobbesianism sees property as first individual and so the subsequent system of handing over one’s right, and thereby constituting civil society and a common good, is only to ensure the greater security of contracts for private ownership.
The Hobbesian scheme sees property as essentially divided from common goods, making anything one does with his own property mostly free from moral considerations. Even an extreme case like price gouging doesn’t strike us as obviously immoral. It might be mean, to be sure, but isn’t “The right answer to [what] a company should charge “what the market will bear” — in other words, the highest price that customers will pay“(?) As with price gouging so too driving up commodities’ prices or paying subsistence wages is simply asking for what one can get for his own stuff, so it’s not as if he is trying to defraud, burgle or rob someone. We can disagree whether this makes such a businessman a shark or a jerk, but it can’t make him evil, right?
