I still wonder why your country needs so many more men jailed than any other country to keep itself civilised. Do you have any idea?
All behavior has a reason and the reason for the crime scenario in the USA can be found in its history which affects the present social situation negatively. What I am about to say applies to all areas of the USA where poverty abounds and crime is statistically far higher than in the materially-prosperous Middle-class Anglo-American neighborhoods.
You see, In a country which abounds in riches beyond all others on Earth it is inevitable that those at the bottom who must observe as those on the top smugly and uncaringly enjoy life to its fullest, feel resentment and feel oppressed. If not by society of those who are in charge-the rich and in the USA the large middle class, then by the seeming injustice of destiny itself.
In poor countries the people can take solace in that the majority are sharing the same discomforts. But in the USA the large prosperous middle Anglo USA class is the one that predominates while the lower classes must look on helplessly. So the situations are not the same.
The African American statistically higher crime rate can be used as an example:
From an historical perspective, black slaves was not the brutally treated as cattle and systematically prevented from acquiring an education lest they feel entitled to a freedom celebrated annually by Anglo USA folks on the Fourth of July. That isn't ancient history and neither is the intense persecution which persisted until the 1960's under Jim Crow a system designed to keep the AAs in their low status place.
Such malicious, systematic denigration in order to keep the AA man down is blamed for present inabilities persistent problems which plague AA communities. So the frustration and the futility which is often encountered in striving to attain equal status with the seemingly-out-of reach Anglo prosperity often manifests itself in crime which is an effort to attain what is deemed otherwise inexorably and forever beyond law-abiding attainment.
The same but to a lesser degree applies to crime in all impoverished USA areas such as the white Appalachian regions and includes the Latino sections that might manifest a higher crime rate than the rest of the Anglo- USA prosperous regions. In short, frustration and the viewing of crime as the only way to proper beyond the glass ceiling which is perceived as unbreakable is the main cause.
So crime in the USA demands a tighter enforcement to keep the whole sordid phenomenon under control and that results in larger incarceration rates.
BTW
This all leads to the emergence of subcultures [of which I was a part once as a teen] which glorify violence and whose members can only gain prestige via demonstrating anti social behavior. In such sub-cultures being BAD becomes being GOOD and being GOOD might involve maiming or murdering somebody to prove it. So it becomes a vicious circle.
