Was prohibition an effective government policy during the 1920s and 30s?
The pros were imaginary. Fundamentalist Christians fervently believed that men would stop drinking and work more. Feminists equally fervently believed that men would stop beating their wives and go disappearing on benders. Medical people hoped that all the diseases related to alcoholism would disappear. They were all wrong. People were so desperate to drink that they would drink even wood alcohol. Prohibition gave a fortune to gangsters and spawned a huge criminal sub culture. Our current prohibition of pot and other drugs is equally futile but the god damned Fundies are too stupid to realize it.
