How do the decisions you make as a consumer affect the economy?

How a consumer affects the economy:

- as a consumer your demand decides the supply, the higher the demand the more the supply

- as a consumer you can potentially influence the prices of a product, high in demand products are usually more expensive than low in demand

- as a consumer the economy was created for your participation and will not survive without it collectively speaking
