Having high ranking people being connected really means nothing, I mean if you were on of the most powerful people in the world would you not aim to work with other people of similar power to actually benefit from the situation. People also all have their individual goals so powerful people work with other powerful people to help realize these goals and if the relationship worked well why not continue it? I'm sure there are many people who are very powerful but don't get involved with other people of the same power because they feel no need to. Really I'm trying to say that people serve themselves over organizations, so powerful people may work together but that doesn't mean there is a great conspiracy, I see it as no different than 'normal' people working together.
