So because the general public doesn't agree with you, they should not get a say in governance. Got it. Also, "global governance" is weak as shit. The idea that the WHO (WTF?), for example, has more control over Americans' lives than the company they work for or the corporations that control state gov'ts is laughable.
Again, if you don't like the way that people vote, you are free to actually get off your ass and get involved in the process. Run for local office, donate money, form organizations, etc.
The effect of all the policy you advocate is to make big businesses more powerful and ordinary people weaker.
