Capitalism is not only a better form of organizing human activity than any deliberate design, any attempt to organize it to satisfy particular preferences, to aim at what people regard as beautiful or pleasant order, but it is also the indispensable condition for just keeping that population alive which exists already in the world. I regard the preservation of what is known as the capitalist system, of the system of free markets and the private ownership of the means of production, as an essential condition of the very survival of mankind.
