Well you had asked for world leaders and these are leaders at world level in their respective fields, anyways i dont know a whole lot of marati, but my point is with Migration one community will gain the other will suffer, if we all make a point to adapt to our new surrounding rather than destroying it, it will help, when parsis landed in gujarat they obliged by accepting customs and traditions of the state where they belong, as you can see they are well assimilated now. But if you displace local people without giving them opportunity perhaps thats wrong, besides maharashtra is a state that is stickler when it comes to discipline and safety.
