Which pair of amendments shows the failure of laws t o solve a social problem?

The Eighteenth Amendment, which enacted Prohibition, and the Twenty-First Amendment, which repealed it, illustrate the failure of laws to solve social problems. Prohibition aimed to eliminate alcohol consumption and its associated societal issues but led to increased crime, illegal production, and distribution of alcohol. Ultimately, the repeal demonstrated that legislative measures alone could not effectively address the complex social challenges related to alcohol use.
