India's political system has all the forms but none of the substance of a democracy. Yes Modi is from a backward caste but his policies are biased towards the upper caste and he is beholden to the upper caste support. The proof in the pudding is how well off the lower caste compared to the upper caste in the last seventy year. And the answer is the lower caste is worst off compared to their upper caste counterpart after seventy years of upper caste rule.
What I am saying is that upper caste don't need to vote because they have complete control of the country. Democracy confers power to the people because you would assume people who vote can affect policies to their favor but this is not the case for the people who vote in India. They are totally disenfranchised and marginalized.
Years ago I talked to a guy who worked there and at that time they were using VB6. I am sure it has changed now. Anyway I read that Epic sue TCS because some of the contractors from TCS stole its code.
