Why only UP, Bihar, is it because these are two most underdeveloped states in india, and ppl comin from there don't come with money, IT IS OK for people like ambanis who are non marathi to live in mumbai and still follow there own cultire, because they have money, IT is OK for so many FII to drain money in BSE because that's money coming in and not going out.
Please answer, i am not from UP, Bihar, but from Delhi, which also has the same situation of migrants from UP, Bihar.
