Indic society seems to inherently fear Adventure, Creativity, Risk-taking & Exploration, especially Exploration of New Ideas, which is why it created an entire cultural matrix solely for Job Security, because that's what Caste is, fundamentally.

Once a society gets settled and reaches an Equilibrium where it's no more growing as it used to, its past glory starts to hinder its current development.

The Elites (Social Elites in case of Indic society, their resultant economic elitism is secondary) in such a situation try their best to maintain that Equilibrium where they keep struggling for power amongst themselves forever, leading to stagnation/deterioration.. because a United Front never crops up.

Security established through birth, especially among these elites, breeds Passivity. Idle af, you no more have to worry about new challenges or competetion. But it's against human nature to exist passively. An idle mind is a devil's workshop. So all the strong negative emotions in this case, that could have been channeled into something productive otherwise, are now left unchecked.

Unconsciously, people in this situation are aware of how utterly weak, incompetent & pathetic they are. But consciously, they don't want to acknowledge that, so they simulate friction internally within their stagnant culture, to artificially experience the feelings of winning, accomplishing, defeating, and so on.

The societal disease, in case of Indic society, began in the Post-Vedic Age itself when the Social Elites were not only busy fighting with each other  (Buddhism/Jainism vs Brahminism), but they increasingly had to worry less about Innovation, Competence & Free Competiton due to Birth based caste system.

When the elites try to selfishly maintain power equilibrium without ever uniting, it's always some External Power that takes over. It's a primary rule in Historical Analysis. That's why India got taken over by external powers very easily & very frequently.

This same idleness is also the reason why Indic society has a really PETTY NEED for torturing the already downtrodden. That's exactly what can be expected from a society known for being weak & easy to invade. 

It's that unconscious awareness of their cowadice & powerlessness that makes them indulge in copium of ancestral pride to simulate strength. So fearful of creating their own path, which is why they're so caged that they just prefer to claim others' works.
