By reference to moral values…

"Capitalism is not a philosophy. It is simply a method of allocating resources based on voluntary exchange instead of coercion. While some say that such a method promotes greed, history indicates that greed is no less present in any other system of allocating resources. Distributism is completely compatible with capitalism to the extent it is a voluntary expression of the desire to make such market exchanges by reference to appropriate moral values and not just profit. Distributism is most difficult to apply in the context of enterprises that need large amounts of capital to compete successfully. Such businesses tend to organize as public companies whose ownership is distinct from management. Such companies have a very difficult time voluntarily expressing values that are inimical to profit maximization. It is not impossible, since corporations can be organized expressing other goals which would be disclosed to investors, but thus far such efforts have not proven all that successful. Instead, non-pecuniary values are imposed via government regulation, which plainly can be blunt and political instruments. It is also important to realize that non-investor corporate constituencies, especially consumers, do alter behavior by imposing their values thereby affecting corporate profits. Imperfect information and imperfect consumers limit the efficacy of such forces, but truly there is nothing about a free market system that renders it inherently incompatible with Catholic values."
