Step One: Create a conflict or problem where none existed before. Make this problem so compelling that others will want to see it solved.
Step Two: Use mainstream media to broadcast and publicize the problem. Escalate its importance and play to the emotions of people to the point where they become uncomfortable enough to clamor for a solution.
Step Three: Get what you want by providing that solution and getting everyone on board with it.
This solution is one the public never dreamed it needed until the conditioning of the first two steps was implemented. Most often the outcome is that people think something great has been done for them, when in fact something harmful has been done to them.
