and Mumbai is Mumbai because of the very same outsiders ....
Also think twice before you say this 2 an Industrialist ....I believe you work in Mantralay or a Sachivalaya ...if you are working in a Private Sector ....think again ....Mumbai is Mumbai because of Entreprenure's who are mostly or 99% outsiders ...if they walk out even you will have to pack your bag and move to Malwan or Marathwada ...wherever your forefathers came from ...
