The comparison of economic power and prospertity in both these countries is well-known: the buildings, vehicles and machines in the former East Germany were much less efficient than those in West Germany. It isn't the quantity of the consumption but rather it is the quality of the usage which matters.\\ \\ | The comparison of economic power and prospertity in both these countries is well-known: the buildings, vehicles and machines in the former East Germany were much less efficient than those in West Germany.
