I don't know where you got the idea that I find the current government unideal
I am in support of the American government system just fine, thank you!
The problem is that people don't make good or bad choices for themselves. They make good or bad choices for everyone. I am no entity to decalare what, exactly, is good or bad, but I have my own perception. It's not that I'd want to "impose" my views on others, but generally I do think that a well-meaning and educated person could look out for the welfare of the people better than the people can.
Look at the President, for instance. Of course, he is elected by the people, but once he's appointed, it's like "The power is yours!" Yes, I stole that from the 'ol Captain Planet. Anyway, imagine a world where instead of a president, the masses simply voted to do anything -- veto, propose a bill, declare war, etc. How often would we do what's best for the country? Most major initiatives by America has been against the will of the masses. And if the people agree, often it is because of the government's declaration of its greatness in protecting the rest of the world.
World War I wasn't fought by us to make the world "safe for democracy." It was fought for our economic interest.
