So the poor commit crimes against each other solely because rich people exist somewhere else and don't interact with them?
Malaysia is oddly anti-semitic for a country with about 0 Jews. I'd expect that if the Jews were causing all the problems, then Jews would actually need to exist in-country. But now you are making me re-think; is it plausible that simply by existing somewhere else, the Jews cause Muslims to engage in bad actions that harm themselves?
I don't understand your general principle. When is it reasonable for one group to blame their actions on the existence of some far away out-group?
