Capitalism is a system of class harmony, in which the accumulated wealth of the capitalists, i.e., their capital, is the source of the supply of products and the demand for labor, and progressively enriches wage earners. For proof, see my Capitalism: A Treatise on Economics.
The
result is that today the average wage earner in a capitalist country has a higher
standard of living than did the kings and emperors of the past, such as
Augustus Caesar, Louis XIV, and Queen
Victoria.
