Let there be no bhayya migration to mumbai or for that matter tamil migration to banglore or gujrati migration to US because just like bhayya takes his preversion around, gujju takes his racism around. But then also let UP and Bihar ban products made by companies headquartered in Mumbai. Once the migration of these headquarters starts from Mumbai to north bhayya states will develop and all will be good. This should be applied to banks and stock exchanges too..
