Ludwig von Mises: "The riches of the rich are not the cause of the poverty of anybody; the process that makes some people rich is, on the contrary, the corollary of the process that improves many peoples want satisfaction. The entrepreneurs, the capitalists and the technologists prosper as far as they succeed in best supplying the consumers." - The Anti-Capitalistic Mentality
