Question

Why do buyers and sellers voluntarily work together?​

Answer 1

Sellers need buyers to make a profit. If sellers create goods and services that the buyer will need or want, they will buy it resulting in profit for the seller.

Answer 2

The principle of voluntary exchange is based on consumers and producers acting in their self-interest. A voluntary exchange between a consumer and a producer makes both parties better off than they were before the exchange. For example: Both parties, you and the consumers, are better off because of the exchange.
