The GP seems to say that that "statistically things are much much better for the historically oppressed" has not caused people NOT to be "weighed down by the poverty, caste and religion of the families they are born into".
India has had the world's largest middle class emerge from poverty in the last three decades, and to somehow claim that economic (& social) upliftment has only benefitted the upper strata is mathematically false. If people were truly weighted down by caste,etc. this uplifted wouldn't be possible
Again, India still reels from literacy problems, and one's likely to see more inequity among the uneducated with regard to social strata.
[1]: I assume that this is the word you seek when you mention statistically
