It doesn't get any better than this,

In America we have a demand economy that is rooted in free market Capitalism. There are so many examples to illustrate this that I could spend all day typing them. But one lesson all folks need to know is just how miraculous free market economies are. Since the free market is full of competitors, they are always looking for a cheaper and quicker way to provide their good or service. When this happens everybody benefits.....and they often benefit pretty darn quick. The very minute one competitor lowers its price one of its competitors will follow suit. And so on and so on throughout that industry's market. Prices drop quickly and often whenever the free market is allowed to do its thing apart from government control.
