I am aware that the Bilderberg group is real but I don't see how it is any more sinister than any other of the myriad of global elite groups. The WTO, IMF, The Fed, OPEC, etc. are all examples of elite interest groups that probably don't have Joe Americas best interests in mind. Most of these elite groups are great examples of the ugly side of capitalism - money rules all and people become mere commodities. Now I'm not going to advocate Marxism as a viable replacement, it has it's problems too, but I think it's healthy to keep an open mind and not get bogged down by labels.
That's who makes up the group.
