It is Schumpeter’s emphatic opinion that within the dynamic stability of capitalist economic system cost-benefit consciousness is the prime social rationality. This social rationality in “the civilization of capitalism” inevitably would generate a certain type of attitude based upon cost-benefit consciousness. Because “capitalist civilization is rationalistic” (Schumpeter, CSD, 127), it is normal for Schumpeter that consumers’ can ‘evaluate the means of production’. They also act rationally in all other realms. In the capitalist civilization, Schumpeter writes, “primarily a product of the evolution of economic rationality, the cost-profit calculus in turn reacts upon that rationality; by crystallizing and defining numerically, it powerfully propels the logic of enterprise. And thus defined and quantified for the economic sector, this type of logic or attitude or method then starts upon its conqueror’s career subjugating―rationalizing―man’s tools and philosophies, his medical practice, his picture of cosmos, his outlook on life, everything in fact including his concepts of beauty and justice and his spiritual ambitions” [Schumpeter, CSD, 123-4].
