I would like to offer the premise that competition is good for an economy in so far that it brings about increased cooperation. That would include cooperation in each business to provide a superior product, and cooperation among consumers who help one another find the best or highest quality product. And it would especially include cooperation among businesses to make sure those consumers they serve in the economy are able to contribute to a growing economy.
When a business pollutes the environment, provides unsafe conditions or rips off the consumer, this is no longer cooperation. And when this is happening too much, it becomes prudent for the citizens or consumers to cooperate in such a fashion as to correct the problem. That is where government is so important.
