It's actually worse than that. Officials and police don't just demand bribes and contributions. They also demand kneeling and grovelling. And even if they were given all that, they might not even fulfill their end of the bribe bargain.How bad is India's corruption these days? Is it as bad as late Ming where people were pretty much openly giving bribes?
But India is not gonna get a revolution anytime soon, because their society accepts this. Their caste system normalizes abuse of power. In any case, Modi have successfully convinced vast numbers of Indians that they are living in a Supapowar Akhand Bharat Empire. So who cares about corruption, when they are living in a Hindu "Golden Age".
