I'm not sure where you learned American history, but your opinions are flawed...
...That was a gift to me from the US Government, because I was born on July 2, 1935.
I think that the one who never understood American history its you
During the Great Depression, crime came in many forms. People across the country read newspaper stories about gangsters. Thousands of people didn't have a job and needed money and food. Labor strikes by miners and autoworkers sometimes turned violent.
In 1929, the most severe depression in the history of the Western World hit the United States. Many Americans, because of the years of prosperity in the past, did not expect it.
The depression lasted ten years until coming to an end in 1939. The recession began with the collapse of the New York Stock Exchange in October of 1929, mostly due to the imbalance in the economy that was obscured by the euphoria of the 1920s. Unemployment was drastically rising
and eventually escalated to a 25 percent unemployment rate.
Throughout this period, unemployment benefits did not exist,
so as the duration of an individual’s unemployment extended (and this usually lasted a very long time),the people of America would resort to extreme measures in order to provide for their families...
...The Great Depression was a time hard felt by all Americans and people throughout the world. It is seen as a time of great poverty across the nation that forced many Americans into unemployment and poor health. As a result, many Americans resorted to crime as a means of bettering themselves and their economic situation.
Theft, prostitution, and alcohol related crime began to increase with the recession.
The hardships that came along with The Great Depression gave the unemployed reasons to commit petty theft so they could save their family. Although these crimes started small, they continued to gradually get worse.
As you can see, in an era when there weren't unemployment benefits in America, theft was the reaction of poor people to buy food, find shelter...
The rich people noticed it.
Then, the rich idealized the way to stop the stealing, because it was affecting banks and manufacturing in general.
With a government in bankruptcy, the rich found the way to cause the government to borrow money and give it to the people in a new program called social services.
With this initiative, the poor people stop stealing when they started to receive benefits from the government.
The rich obtained double benefit, which was no more thefts plus making profit with the loans given to the US government, which were mostly with high interest.
At the end of the day, of course that many people not only obtained benefits but abused of the system.
For example, Public Housing was created as a temporary shelter at low price for low income families and individuals.
I knew families who have lived in Public Housing for generations. The mother with new born children all the time, the older daughter living in the same Public Housing complex with children as well. Mother and daughter "making extra money" from boyfriends who live illegally in those apartments, ha ha ha... and no way how to control it... even with today's technology and cameras in those living complexes, they manage to keep doing it.
Same with food stamps, medical services, etc.
Any new administration take away those social programs, and what it happened in the Great depression will be nothing in comparison to what can happen in today cities.
At least, when you were born, even in cities, people used to have chicken in their backyards and have something to eat even when working days were sporadic... but today, no chicken, no money, no unemployment services, no welfare, no food stamps... beware!
