Yes Maharashtra especially Bombay has got many easy sources of income, thats why poor people from other states come to Bombay.
People are coming to Bombay for daily bread and butter, coz it lacs in their hometown. At some time it is good that they are coming to Bombay, why, because empty stomach can force you to do anything even will prompt you to become terrorist. If so then it will be harder and very tough situation for every Indian.
All and all India must have strict, infact very strict Law and order.
This will lead to stop this kind of activities and can stop corruption in all the areas of the govt and private sector.
If laws are strict nobody, not even Raj will dare to do this kind of activities.
