delhi does not have 75% of its population of outsiders. mumbai does. so mumbai's problem are more severe.besides sheila dikshit too criticised migrants recently and blamed them for delhis problem.you can't hide from the truth that uncontrolled migration is root cause of mumbai's problem.infratructure is unable to catch up with the speed at which population grows. migration proves that the states from which the people migrate have failed to take care of their own people. do maharashtrians migrate en-masse to other states ? we dont need shiv sena to tell us whats happening to our city.
