Without calculation, economic activity is impossible. Since under Socialism economic calculation is impossible, under Socialism there can be no economic activity in our sense of the word All economic change, therefore, would involve operations the value of which could neither be predicted beforehand nor ascertained after they had taken place. Everything would be a leap in the dark. Socialism is the renunciation of rational economy.
Ludwig von MisesThere is but one means available to improve the material conditions of mankind: to accelerate the growth of capital accumulated as against the growth in population. The greater the amount of capital invested per head of the worker, the more and better goods can be produced and consumed. This is what capitalism, the much abused profit system, has brought about and brings about daily anew. Yet, most present-day governments and political parties are eager to destroy this system.
Ludwig von MisesThe 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.
