I think Mr Raj Thackrey's concerns are misplace. I understand his concern as I am a witness to such migrant poplulation of not only Biharis but also illegal B'deshis putting a huge pressure on the infrastructure of the cities. However, it is not a solution to harrass and beat up poor vendors/taxi drivers. Poeple will still migrate to Mumbai. Also safety & securty of Maharashtrians elsewhere in India will be at a risk. This creates a doubt on Mr Raj's actual intentions. Only solution is to create jobs in the respective states to avoid such huge migration. To do this Amitabh is trying to help UP govt by being the brand ambassador/Opening schools etc. If this works, with increase in Job oppurtunities in UP/Bihar, Mr Raj can hope the migration comes down. So he should be thanking AB instead of critisizing him.
