   Generate profits

Explanation:  In a perfectly competitive market that involves the absence of a monopoly, prices are formed so that all competitors make a profit. The absence of a monopoly means fair conditions for everyone, and anyone, according to their abilities, investments, can make a profit.

A perfect competitive market, in other words, means determining the market conditions in which all competitors can participate.
