There's no good system of government, which is why our forefathers tried to make the government as weak and unintrusive as possible. A republic is bad because the peoples' interests aren't directly represented, a direct democracy is bad because it takes far too long to get a national consensus vote on anything, a monarchy is bad because the person in charge is the only person who's opinion matters, socialism / communism are bad because they crush creative industry and promote corruption in the government, etc.
