How do you get money, you get money by giving away something of value. Value is price, and it is decided by supply and demand aka the market. Money is a system to exchange value, but why do we have to exchange value, why can we not give away something of value without getting something in return. This might be a feature/flaw in nature or simply a conditioning, but because of this we have systems to exchange value.
Governments are described in terms of economic systems, value exchange is a fundamental protocol of society it surpasses language, religion, race in its influence in our day to day living.
