Its part of the brainwashing to preserve the illusion that they live in a real Democracy even though there has been a duopoly on Power for way over a century and that they are Free even though only a small number of them is born in wealthy enough families that they can actually do what they want, whilst everybody else has to do what they have to merelly to survive and are even constrained in that (for example, if they invade long unused land, to build their home and do subsistence farming there - i.e. try to have freedom via self-sufficiency - they will be kicked when the owner calls the "authorities").
Also treating the Constitution as almost sacred means that people can't challenge or even just criticize the very mathematical rigging that makes Power in their country be controlled by a duopoly (and hence not a Democracy) because it was set down on said Constitution so doing so would be challenging/criticising said "holy" Constitution.
Thinking people should always ponder on the answer for the good old Cui bono? ("Who gains from it?") question (so old it comes in Latin) whenever something or somebody is relentlessly portrayed as beyond questioning.
