That's why we were a republic. A wealthy white male republic, then a white male republic, then we sort of let some black people vote, and then we eventually let women vote, and we begrudgingly became a democracy. At least, in principle, according to this countries legal codes.
But really, a country will be run according to the capabilities of the people living in that country. If the people in a country are informed enough for a democracy, they'll probably end up with a democracy. Revolutions are made this way. If the people of a country become too ill-informed, as they are today, and not capable of having a democracy, than the country won't be a democracy. It'll be corrupted, and it could easily turn into a monarchy, or a oligarchy, or the plutocracy we have now. If the people of this country were to become informed enough, than it could elect the right people, and take control back of the government. The military would almost assuredly make sure this happens (so sort of a revolution, but without actually needing to fight a war).
