To expand on this, you are likely to do favors for people you know even if it will harm other groups. This happens a lot. There are conspiracy theories galore about big governments and their level of organization to keep the populace out-of-the-loop, but I think it just comes down to rich people who know each other and help each other out at the expense of out-groups. It's an organic process, and not really organized in a strict sense. The Clinton foundation is a good example of this (watch the Clinton Cash documentary).
