What is meant by consumer sovereignity? Why it may be necessary for a government to intetvene to protect this sovereignity?

      People are:

            maximisers of utility

            rational

            competitive

            selfish

            do not like work

      All factors are owned by consumers and price is determined by market forces-price system.

      Defn.of sovereignity: consumer decides what is being produced by spending money on those goods.
