The elite faction of Jewry has gone to incredible lengths to keep the tribe together because the tribe is the source of their best assets to further their goals. They might use gentiles for their convenience, but a gentile always operates on their personal ambition and expecting certain rewards while the members of the tribe work for the sake of the tribe on itself, and will always be more trustworthy. I don't think the elites care for the tribe in any other way than in this sense of self convenience. In fact probably the Elites consider themselves worthy of their position by blood ties while the lesser brethren are not always necessarily pure blooded, wherever this actual elite blood may originate from ( I am not certain of it, possibly a long lineage, perhaps of a mythical nature, now deemed semi divine in some form).
