Historically Australia proves a good example of this.
There was an interesting book a few years ago ( The Great Wave, here's a review which tied, among other things, increases in crime to a decrease in real wages and an increase in income inequality.
Of course, crime has nothing to do with the breakdown of the family unit, destructive socio-cultural attitudes, and a dependency/entitlement mentality fostered by left-wing social engineers. And laziness never ever has anything to do with it either, I suppose. It's easier to demand a check from someone else than to work, study, and aspire to do better.
