What?? What point are you even trying to make, now? "More black people would play hockey if more slaves had been imported to Canada and Scandinavia"? Sure, probably, but that's now a completely irrelevant hypothetical to the posed question of "is there a economic background connection to the likelihood of bankruptcy after exposure to extreme short-lived income streams?"
Um, I think I said nothing of the kind. I believe you need to reconsider how you approach different topics. People are free to move about these days you know.
