I can’t see India ever becoming rich and prosperous. Its culture is too low trust for India as a people to fix itself. L.The best thing the West can do is seal it off and prevent any immigration from anyone but Christians.
India can never develop a burgeoning Middle Class because the Hindu's caste system forbids upward social mobility. If you were born poor it's because of your deeds in past lives, which means you deserve to be where you are.
This also is why Hindus don't proselytize. If you were meant to be Hindu, you'd have been born that way. Any attempt to convert non-Hindus is viewed as rejection of Hindu canon.
It's not unlike official government policy in England was for centuries. There were government-supported social and financial barriers designed to keep the poor poor.
It sort of begs the question whether the Indian government would want to change the status quo if it could because as is human labor is one of the cheapest commodities you can buy there.
