It can be easily admitted that the question of peace is not primary to Economics. Dr. Marshall and other economists who followed him have conceded that, while the question of morality may also be considered, rnorality was not an imperative.
Keynes said: When we become prosperous economically, then alone will arise the occasion to think about morality. The present is no proper time for that. Whatever is wrong today might also be useful at the moment. Economics is based on the concept of utility and, therefore, it does not consider there is anything wrong in that. What is useful is right and is desirable, it is maintained.
