I never understand why people just toss off groups like Bilderberg as if they are not important.
The Bilderberg Group actually exists, like the neo-Nazi jerk-off fest that happens in Davos every January. It's not a conspiracy theory that these arrangements and groups exist. They do.
Where it gets into "tinfoil" territory, as I see it, is when people see these gatherings as crucial rather than symptomatic. Sure, some of the worst people in the world meet every year, but they don't rely on that particular meeting all that much. Drop a bomb on the next Bilderberg gathering, and I won't feel much sympathy for the people wiped out, but you're not going to make the world dramatically different. The few hundred assholes killed will be replace by some other few hundred assholes, and life will go on as normal.
Bilderberg-type cabals are an appealing fantasy because they admit a world in which killing a few hundred people can liberate humanity from scarcity, corruption, and dictators. It's a video-game fantasy in which killing the Big Bad (after leveling up against his minions and henchmen) saves the world. Unfortunately, that's not how things actually work. There is no one Big Bad and the few hundred who play that role are still symptomatic (i.e., they exploit the low level of cultural and moral development of our species, from its inception up to now) rather than critical.
How robust the global-elite network actually is, that's uncertain. I'd love to believe that it's fragile, but the idea that it relies on a specific gathering would make it more fragile than I can really believe. My guess is that these meetings (Bilderberg, Davos) are more symbolic than anything else. Getting invited means that you've "arrived" in the subculture of elite global evil, so it might be personally important, but it's not like the world is run from them.
Besides, these people don't need shadowy conspiracies to coordinate evil. They already own such a large share of society's resources, and they can get away with slimy activity in the open, so "smoke-filled rooms" really aren't necessary.
