Well we must accept that crime is an essential part in society, an ideal society without crime is simply surreal, why? Because there is always the unbalance between people and it become more complicated every day, every step in humanity's development, why? Because our resources in the Earth are limited so then we must fight, work for it. The criminals are just doing what they suppose to do for surviving, it help maintaining the balance between the rich and the poor.
If you want to divide equally the resource for everyone, welcome, you've got the 1st step of communism and you realize how stagnant your progression is, because people then have no motivation for self-development. And if just only 1 people tries to get out that system and becomes different, envy, greed will appear and grind down what you are trying to build.
