The more effective approach by far is to condition people from childhood into believing that the ability to select from one of a few impotent political identities, all of which lead to the slightest variations of policy conclusions within the field of pre-determined acceptability, represents the universal best possible form of governance and the purest instantiation of such high-minded ideals as Freedom, Liberty, and Justice.
This way you can mollify a population into accepting almost anything as normal: endless wars, hundreds of thousands of preventable deaths, lifelong debt, a constant struggle to afford housing, education, and medical care, etc. You can convince them at will that any rival is a tyrannical regime under a capricious, childish, genocidal maniac, and that any evidence to the contrary should be dismissed with self-satisfied smugness as coerced or compensated state propaganda.
