1. First Feature Film was produced- directed by Dadasaheb Phalke, thats way Film industry is here. That doesn't have any relation to the reservation. 2. Nobody forced them to stay in mumbai, they are not doing anything great for society. 3. Nobody forces the companies to sell their products nationwide and pay salaries in Mumbai, that's their own policy and doesn't have any relation to the reservations. Companies can't open offices in each state to share the revenues.
Nobody asks quota for localites except maharashtrians, because officers in private and government sectors give preferences to their own people and marathis are discriminated everywhere.
