Quoting the FTC https://www.ftc.gov/advice-guidance/competition-guidance/guide-antitrust-laws/antitrust-laws https://www.ftc.gov/advice-guidance/competition-guidance/gui... : "[...] antitrust laws have had the same basic objective: to protect the process of competition for the benefit of consumers, making sure there are strong incentives for businesses to operate efficiently, keep prices down, and keep quality up." A monopoly that abuses its power is one example of anti-trust; it is not the definition.
