It can reduce overproduction, increase effective demand and facilitate the balance between the demand and supply, and prevent the frequent occurrence of economic crisis. All the creatures of the God are there for a reason. The amount of production is based on the amount of currency. But some parts of currency are transformed into savings, and savings cannot be turned into investment immediately. The entailing overproduction breaks the balance between the demand and supply, and results in economic crisis. In modem society, it is the social security or those "lazy bones" that represses and eliminates the overproduction, which can be expressed by the equation: Savings = Investment + Social security (consumption). In this way, the balance between the demand and supply is realized.and the social production and life can continue in a normal way.展开更多
