That is basically a longform way of saying "people will steal if their personal economics makes stealing rational". While extremely true it doesn't give a toehold into the problem to decide what to do next.

The question here is really what specific policies and cultural forces are shaping the economic realities that these people are living in. If nothing else, we should ask why someone isn't having great success hiring a few thick-knuckled train robbers away from their life of crime and running a very profitable security business.
