"With the country mired in the Great Depression by 1932, creating jobs and revenue by legalizing the liquor industry had an undeniable appeal."
During this time period, America was in the midst of the great depression. Even though this might not have been the best thing, but some people looked to alcohol as their escape. By taking away alcohol it also destroyed jobs, which there were already so few of. By brining alcohol back the government can take tax out of it and try to make one more way of making money.
In this carton it depicts what crime was like during this time period. With alcohol being illegal, all that did was create a market for the underground sale of alcohol. Organized crime rings ran cities, politics, police, they had everyone on their side. When the 21st amendment came out and made alcohol legal again, it cut the largest flow of money to all of these organized crime rings, which I believe is one of the causes that there were fewer after the legalization.
