"The only way a person can make a profit from others is by not paying them a fair wage for their labour. If wages were perfectly fair, nobody could make a profit. But the extraction of plusvalue from other people's wages is what makes profits possible."

Actually, profits and wealth can be measured in other ways. All can profit either equally or unequally. Money itself is only a unit of exchange giving relative value to a wide variety of goods and services.
Forgetting about the monetary value of goods and services for a moment, a group of people may utilize a division of labor in which some build, others farm or hunt and others maintain the families and education while all in the group benefit and advance as a society.
Society is not initially built on a system of competition demanding winners and losers. The winners and losers approach is artificial and, when taken to the extreme, detrimental.
Money itself does not create this extreme. Corporations can profit while paying its employees sufficient wages for them to do well and accumulate property and or savings.
