More than 50% of Indian MPs are lower caste and minorities https://www.indiatoday.in/india/story/only-39-mps-are-politi...
Indian PM and president are from backward caste. Reservation for lower caste in government educational institutes and jobs is more than 50% https://en.wikipedia.org/wiki/Reservation_in_India#States.
So much for upper caste having complete control of democracy and lower caste being "the most disenfranchised and marginalized communities". I'm not saying all problems are solved. It's a work in progress like any other democracy but progress is being made slowly and steadily.
