How about we take some real examples. How much more likely is a poor person to murder someone? Beat their wife? ... you know the answer already, which of course was the point of these whole "rich people are antisocial" posts. It is attempt to try and subvert some inconvenient truths - truths that need to be subverted in order to push a certain ideology.
Anyway, from a personal note, I grew up in a very working class area, and I have been to many third world countries. Let me tell you, poverty, real poverty that is, really turns people into absolute pieces of shit. There is no judgment here, it would probably happen to me or anyone else reading this if they were in that situation, but poverty really ruins peoples morality and decency. That is a fact.
