I thought about the source of wealth and the nature thereof; I wondered where money ultimately comes from. After some thought, I realized that there is no more wealth than is ever present at a given time. Time can be exchanged for money, money for gold, gold for food. But the cause of economic crashes and turmoil is not caused by scarcity of resources or misspent money. A healthy economy is one in which wealth is ever-flowing, always changing hands. It is only when people hoard resources, be it money or other items, that the flow is inhibited or stopped completely. At this point, an economy can stagnate and even falter completely. Therefore, greed is the cause of economic downturns and recessions. Social competition and selfish behaviors are punished by the delicate system upon which we depend for our livelihood. An economy is inherently selfless and unbiased, in contrast to human nature; perhaps we can learn something from it.
