what is meant by first right ? The UP /Biharis are doing no one else does ( taxi, auto, secuirty guards, construction workers )and that is why they are demand everywhere including Marathi industrialists ( if there are any ) . Also why can't it be a rule that only a son of the soil can run a company so that Ambani's go back to Gujarat, Mittals to UP/Rajasthan, Tatas to Persia and so on. Hindi movies can have only actors whose mother tongue is Hindi/Urdu - Gowarikar makes only Marathi movies and so on - and shooting done only in Hindi speaking states. You mean to say brokerage houses must sack all gujarati fund managers and replace them with Marathis ? or TCS hires only Marathi engineers even if they can't write a line of code.
You are being just silly because you don't even know what you want.
