There is no denying that migrants have had a huge hand in making Mumbai... Howefver, there is something called a saturation point... And Government investing equally in all regions?? That's a laugh... Are the work cultures equal in all the regions of the nation? In Calcutta, a dog pisses on the streets and Mamata di will call a bandh... with 100% success... In Mumbai, a train blasts kills hundreds and the very next day people are back to work... I personally am against this attitude because this is precisely why the Centre takes Mumbai for granted... But it is this attitude which attracts investors here and consequently job opportunities are created making people like you come and work here...
