I don't know who the ones at the top are, all I see is that there's an agenda that has moved consistently towards one direction, and many of the self made megarich and high ranking politicians start pushing it once they get to a certain age and certain level of wealth and influence. It's obvious that someone is telling them what to think, what to do, and what the plan is.
Or perhaps there's no one calling the shots, and it's all just the way the system is set up. But being that it's been so long and the direction is so clear, I would highly doubt there isn't any group that's behind this. But again, it's not like you'd hear about this group, their members and their plan on the evening news.
This is why talking about such entities as the illuminati, the bilderberg group or whatever, is counterproductive, as it is exactly what they want. Surely these organizations play a role, but they're not the ones designing the plan.
