Abstract
That capitalism is a superior economic system because it elicits productive effort from individuals by utilizing the desire for material improvement, is a contention that can be defended if it could be established that this desire is a universal human motive and is to be found in non‐capitalist as well as capitalist societies. In addition, it can be argued that within a market economy, if men pursue what is in their own interest, their actions are likely to have the unintended consequence that, many others benefit; for under capitalism, one man's gain is not necessarily another's loss. Both these points are raised in reply to Richard Schmitt's alleged refutation of ‘the psychological defence of capitalism” {Inquiry, Vol. 16 [1973], No. 2).
