Imagine the kind of people who would come from a culture like this. They're not in Mexico any more. They're here.
This was all about the time of Jesus. Don't ask about what sorts of things were going on with the European Ancestors of most "white" Americans at that time. Or what their stay at home cousins did circa 1939-1945. Or what those other eastern European relatives of the Scandanatians (The Rus) were doing from about 1920 onwards. Starving Ukranians was the least of it, although probalby accounted for the biggest "bill".
