We are living in a republic and states do not have any boundary. Tomorrow a new government may come and devide your state in 3 parts. Besides within a country you can not and should not stop migration by beating poors on the road. Speaking specifics, the condition of Mumbai got detoriated because of negligance from government. Building infra structure is an on-going process. Even if you stop migration still u have to keep on building infra structure. Tomorrow it may happen that population may double even without immigration. Then what is the solution. The solution wont be killing off or throwing 20% population in see, instead the solution will be to make in better infra structure and keep pace with rest of the world. I have lived in different parts of India and at many cities they kept up with growing demands. Delhi right now is 10 times better than what it was 15 years back. There also migrants come from all over India. Mumbai seems like development stopped 15 year back and now people of Mumbai have come down to the levels of politics being played by Hindi Heartland. And shamefully they are feeling proud of it.
