"It is not from the benevolence of the butcher, the brewer, or the baker that we expect our dinner, but from their regard to their own interest."
- Adam Smith
We are all consumers and creators. Some people are more creators than consumers while most people are more consumers than creators. Consumers are the ones controlling the demand while creators are the ones controlling the supply.
Most people prefer to be consumers rather than creators and that's what makes capitalism seems not to be working by many. However, the problem is not with capitalism but with the people themselves.
