What? If?

What if democracy is just an illusion?

In the US, the dominant political discourse consists of ideas put forth by the ruling class.

Then a lot of tl;dr, ending:

And perhaps there's the real problem. If you believe the US is a democracy, if you believe in the rule of the many and not the rule of the few, then the Citizens United ruling could not be more troubling. But what if this is not a democracy? What if this, as Dionne suggests, is an oligarchy of billionaire capitalists? More horrible to ponder, what if democracy is yet more intellectual cover, another one of those illusions, for the exploitation of American workers?

Then the theory of the ruling class fits perfectly. Citizens United and the United States were made for each other.
