Conspiracy is the equal and opposite reaction to Propaganda.

Propaganda so crude any thinker sees through it.
Conspiracy so crude any thinker sees through it.

Propaganda so convincing it resists dismissal.
Conspiracy so convincing it resists dismissal.

Neither guarantees truth.

The only question is perception:
Do you own it, or does someone else?

What is true, is this:
The dollars you spend are fiat.
The leaders you elect are figureheads.

Memetics.
