Mumbai will not be killed by corruption or politicians it will be killed by the sheer weight of the influx of population entering the island from all directions(except sea) The influx is maximum from Bihar and Uttarpradesh where highpopulation and low opportunity has makes them look for this financial mecca for survival.Each migrant entering the metro sends the success story to others back home and invites them to join.Each person adds to the fragile infrastructure including transport(read local trains)solid waste/ garbage and consequent monsoon disasters.Our Hon courts have passed orders on infrastructure gear-up but have yet to take up suo-moto action on population influx .It's the time bomb that will ultimately sink this city.Politicians will never raise this issue as they are getting additional captive vote banks for their own survival.
