A democracy, technically speaking, is a place where the majority of the people get to decide on policy.

Given that, I don't think we actually have a single real democracy in the entire world today...though we do have a great number of places pretending to be real democracies.

What happens in those places is that a very small and wealthy power elite controls all the main political parties, and the mass media outlets, and the police, and the government and armed forces....by the power of their money...and through the inter-personal connections long established in that wealthy power elite. The elite holds "elections" at regular intervals, and the public goes out and rubber stamps some of the pre-picked candidates that the elite has selected, funded, and publicized through the media.

The candidates, once elected, do exactly what the wealthy elite has put them there to do. That is, they serve the interests of that same elite. If the elite has created a massive public debt that threatens to break the economy of the nation, then the elected candidates bail the elite out and they pass the bill on to the general public in the form of further national debt.

And the game goes on.

That is not a true democracy. It's an oligarchy of special interests.
