You noticed all the negative things about India and exaggerated them like hell. I mean yes I would find these in the worst corners of India, but the whole country is not even half of what you described.
India is developed, beautiful, and way ahead of your explanations, so I am sorry dear. I hope you had a better itinerary, probably someone just made you roam around the slum areas and not the real India, or it was you who wanted to do that on purpose.
Never mind, there are similar sides to Paris as well, but if I visit Paris, I will spend a handsome amount of money I earned in a very high-paying job I do in INDIA and enjoy all the best parts of Paris, ignoring what isn’t pleasing to my eyes, because I choose happiness, unlike you maybe.
