Many of them didn't decide to be poor, the super-rich did. Blame where blame is due!
Well put. People who steal do it for one of three reasons only:
1: Kleptomania - these people are mentally ill by definition.
2: Poverty, and in a society that continually uses the most advanced subliminal messaging it can in order to make them desire material things the poor could argue that they are brainwashed into the criminal act.
3: Greed - The very thing that drives politicians and bankers to rob us all through the expenses system, financial manipulation and even worse methods. Greed is arguably the biggest problem of them all as it's the one that creates the poverty.
