One thing's for sure. If someone is going to develop a single world government, it won't be this group
I actually believe that a corporate structure would have the best chance at a world government. Not the same setups as most of today's corporations, but something similar. Instead of answering to voters, those in power would have to answer to shareholders, who would be all of the population.
Also, the comments about individualism/state-ism (?), I also think that a shareholder/voter situation would satisfy that requirement. If the government does better, you make more money! If the government does poorly, you get paid less. Something like this would be more inclined to get most people to pay more attention to the goings on of whats around them than simply if you show up, you get paid. Regardless of what is done/not done, you get paid the same. IMO this is why Communism in particular and any other socialist government in general does not work. This is also why I'm opposed to labor unions. Show up, get paid. Regardless if whether you actually work or not. Don't get me wrong, I believe there is a place for unions but not to the degree that they are now.
Eg: Several years ago (mid '80s I believe), a disgruntled worker for the National Film board of Canada, brought a handgun into work and shot one his co-workers. The victim didn't die (thankfully) and the attacker was put on a temporary leave. After which (don't recall the time frame) his job was still waiting for him. Under the terms of the Union, he could NOT be fired for shooting a fellow employee.
