The Federal Trade Commission (FTC) oversees national economics by promoting fair competition and protecting consumers from deceptive business practices. Its primary roles include investigating anti-competitive behaviors, enforcing antitrust laws, and facilitating consumer protection initiatives such as truth-in-advertising regulations. By monitoring market activities and preventing monopolistic practices, the FTC helps ensure a level playing field for businesses and upholds consumer rights. Additionally, the FTC conducts research and provides educational resources to inform both businesses and consumers, ultimately contributing to a healthy and competitive economic environment.
