The rationale here is to advocate that yeh government should save more money during good times and should spend it when really in need like in bad situation and crisis period. I do agree with Keynes and with his idea of this saving and spending money for the ultimate growth of the economy. In this way, there will be suitable balance in the nation as well. I believe that the recommendation of Keynes is based on the classical economic theory that provides an idea of ending depressions because of low economy of a country.
