As regards to population, there is nothing new to add here. It is no different to migration anywhere else in the world. You may hate the migrants, but the thing is that it keeps the economy ticking. Would all the Reddy landlords in Bangalore want to go back to the 80s and lose the billions they have made in real estate collectively building apartments, PGs, Hospitals, Malls? Will the thousands of Kannadigas who run restaurants feeding the Bangaloreans want to go back to the days of handful of darshinis in the 80s? They have their own growing populations and economic activity takes care of them too. It is easy for a rich old Bangalorean to cry about paradise lost, but does he ever think who would have given jobs to poor Kannadigas who now at least have blue collar jobs due to economic activity? It's not that black and white. The resentment happens because of planning failure and greed of politicians and municipal corporations, who have allowed an urban mess to get created. The urban expansion could have been managed better, with no-build zones and incentives to move to newer areas. Why didn't they do that? City administrations in developed countries are at their wits end trying to arrest the stagnation of their economies. We have the exact opposite situation.
