I wonder, hotenough, if the US would ever be able to do anything positive in your eyes---even if it actually did.
Democracy, at any rate, back to the original subject, getting away from America-bashing:
The flaw in democracy is that it gives the People what they desire, but what they want at the moment isn't necessarily what's best as far as the People's long-term interests. And the People are fickle. A direct democracy would get out of control, that's why we have republics (or crowned republics/constitutional monarchies with representative government, like Canada). The leaders need a little leeway to make decisions, sometimes independent of the wilder winds of public debate, believe it or not. It's a flawed system, but it's really the only thing that's better than dictatorship/despotism/whatever you want to call the nastier forms of government.
