The basic issue is caste defined as the absence of personal responsibility and freedom from consequences.

That has been the default case of governance since, at least, the development of settled agriculture.  But it has usually been wrapped in religious justifications. It is what Voltaire meant when he said "Religion began when the first Priest duped the first peasant."

Regardless of the ideological justification, that behavior is the one at least 80% of the people expect, based on long experience.  That expectation is written into their brains and, so long as there is a credible "external threat" and/or their situation is not totally intolerable, they actually find comfort in familiarity.  Pathetic but true.  Our social abilities are closer to those of ants than most will believe.

"It is not necessary to have hope in order to persevere."
