The problem is that with the commencement of rule of the Dravidian parties, there are virtually no jobs in government and government related institutions. Brahmins have virtually been thrown out of medical education. Thus brahmins were facing a bleak future. The rise of software industry has been a godsend gift for them to lift them out of poverty. It is okay to preach brahmins not to go abroad but who will like to die of hunger and penury even in one's homeland. Brahmins getting jobs in gulf countries, Malaysia etc which have a sizeable Indian population maintain their culture. We should only expect that to the extent possible, expatriate brahmins should try to maintain their culture. Incidentally how many brahmins living in TN maintain their culture?
