It's not a part/force of Indian culture. Indian culture is much higher and broader and doesn't cherish /encourage any of such discriminatory social models.

It's the colonialism, politics and the constitution of (free) India that created these gaps in society.

In Vedic culture (which is Indian Culture), the society was divided in four (Varnpratha) by their work, not by their birth.

But when India was colonialised, this system to was deliberately broken to divide and rule.

India got freedom in 1947, but this again wasn't addressed because of politics of vote. Some castes were given reservation for 10 years initially but the reservation in jobs and subsidies still going on and is given 50% to scheduled castes and tribes for they are still regarded as deprived and poor; which they all had never been, nor they all are now.

The reservation did give them jobs but by marking them as deprived, poor and oppressed made them judgemental about themselves and other castes and tribes.

TBH noone is trying to address it for and when anyone tries, there can be horrific results. Half a billion people will be fighting another half a billion on streets.
