Ancient Greeks had slaves, Romans had slaves and today's America has millions of slaves.
The logical fallacy people always make when talking about democracy is they always assume "demos" means everyone, when "demos" has and will always be only a small group at the top, while everyone else are their slaves. By extension, when America forces democracy on a country, the "demos" isn't the people of the country, the "demos" is still the same small group in America. Democracy literally means American elite rule.
