First off, the mob isn't as weak or as disconnected from the old country as many people here seem to think. Recent busts and investigations have proven that. Secondly, I don't see any reason to water down LCN any more than it already is by recruiting non-Italians. My main reason for this is because they can still be very beneficial and powerful associates without diluting the ranks and without the extra headaches from internal mob politics as well as the added target on their backs. That doesn't benefit neither the associates or the made men.
