⭐ Why Does This Matter?

Short-term: Prohibition's most immediate consequence was the explosion of organised crime. Al Capone's Chicago empire earned $60 million per year. By the late 1920s, New York City had 30,000 speakeasies — more drinking establishments than before the ban. The 1919-1933 period saw the birth of American organised crime as a permanent institution that persisted long after Repeal.

Long-term: The failure of Prohibition became a landmark lesson about the limits of government power to change social behaviour through legislation. The Mafia networks established during Prohibition — bootlegging, corruption, territorial control — survived its repeal and evolved into the organised crime structures that plagued American cities for decades. The erosion of respect for law also contributed to a broader cultural scepticism toward government authority.

Turning point? Yes — Prohibition accelerated the growth of federal organised crime from a local problem to a national one. Its failure in 1933 also marked a shift in public attitudes: the belief that government could legislate morality had been decisively tested and found wanting.
