Money is scale: Larger scales can ignore small impacts. The poorer you are, the greater the complexity. The wealthier you are, the lower the complexity. 
Example: How much money can you loose before you care? $0.1, $1, $10, $100, $1,000, $10,000 ...
Example #2: FU money, and generally being able to chose who to interact with.
For those who want a more technical discussion: Kinetic energy (how fast something is moving) is also scale, potential energy is a kind of potential scale, e.g. in gasoline and other energy sources. Money in society is a construct with potential scale.
