Ideology fails for two reasons—first, because it is based on falsehood about human nature, and hence can’t help but fail; and second, because as those falsehoods become more evident, the gap grows between what the ideology claims and the lived experience of human beings under its domain until the regime loses legitimacy. Either it enforces conformity to a lie it struggles to defend, or it collapses when the gap between claim and reality finally results in wholesale loss of belief among the populace. More often than not, one precedes the other.
