No. Profit is the reward for investment. An investor defers gratification and uses their money instead to try to make more money later. Profit is the compensation he or she receives for doing this. Part of it takes account of risk, the risk that the investment might not pay off or that the investor might lose the money they put up. Part of the profit is reward for taking that risk.
The notion of profit as exploitation derives from a mistake made by Karl Marx. He supposed that value resides in objects, rather than in the mind of the beholder. Because he thought it resides in objects, he asked how it got there, and answered that value represents the labour it takes to make something. A price charged above the value of that labour represents "surplus value," and is exploiting the workers who make the object. Hence comes the notion of profit as exploitation.
In fact people value things differently, which is why they trade. An object's value to me might represent the other uses I might have made of the money, had I not expended it in producing the object. If someone values it more than that they will pay a price that includes a profit for me. Far from being a sign of exploitation, profit serves a valuable human purpose in motivating people to produce goods and services that are of value to their fellow human beings. It directs us to serve the needs of others in seeking a return for ourselves. The butcher, the brewer and the baker might seek their own reward in terms of the profit they make, but in doing so they provide others with meat, ale and bread.
Profit is legitimate, and sends signals to others. If some areas of production show high profits, others are motivated to enter that field themselves and bring extra production onto the market. The competition with other producers will generally act to restrain or reduce the high profits.
