How did the eighteenth amendment outlawing alcohol both reflect and deepen the cultural divisions?

The eighteenth amendment outlawing alcohol impacted the alcohol consumption of the general public. Decrease in alcohol consumption happened in low income families. However, illegal production and distribution of alcohol gave rise to organized crime and because of this consumption also began to rise.

The most identifiable person who benefited in this amendment by defying it was Al Capone. He earned millions from the sale of illegal booze and in turn ventured out to other illegal businesses like prostitution, drugs, and gambling.
