Why don't India's low castes immigrate to tiger pounce?

On the one hand, policy immigration is very restrictive and basically not allowed.

On the other hand, India's caste status is low, there is no stable source of income, and immigrants basically have no money, which is also very realistic.

There are also long-term religious beliefs, historical and cultural factors and other profound influences on every Indian. The power of faith ",India is a country above national religion, almost 80% of people are Christians, they firmly believe that as long as they are sincere, they will be blessed by the gods, and this life is also for better repentance, and the next life can change their true identity, so they are willing to bear the pain they are suffering now.
