The market is like a language that conveys information to everyone. Everybody consumes, so the voice that is heard most plentifully in the market is that of the consumer. That is good because if that voice is stifled or ignored then many, many ('the majority'; the 'masses') will suffer. The producers are relatively few but if they listen to the language spoken in the market they will hear what is wanted. Those that listen and then serve will succeed and will at the same time honor the sovereign voice of the consumer.
Those who oppose the market prevent the language of human communication and coordination from functioning properly and interfere with the advancement of social cooperation.
