I would put poverty and income disparities on the first positions. Countries like USA have a huge prison population and they still face high crime rates on some regions. I suspect that historic criminality may play an important role too, since it influences more and more groups of people and make them to consider crime as a feasible or even natural alternative. I have some really good-hearted, hard worker friends, who already had some involvement with crime when younger, just because they were influenced by friends on the slums they lived on. In their circumstances, that simply felt to them the natural choice to make. Maybe I'm being too naïve, but I believe a big revolution would happen if the government started to make itself present not only with law enforcement, but also with quality public services and, very importantly, good schools. I think that that could break the endless cycle of bad influences the poorer youth are currently under.
