Nice one... Will it survive for 50 yrs...And India as of 2020 is the 6th largest economy in the world. But does that matter in actuality ? A majority of Indians generally live and die in miserable conditions and many don't even question that. As our Chinese member @TaiShang put it :

Sad.
By the way, Hinduism is as foreign to India as Islam. Hinduism just preceded Islam by 2000 years or so.
