What Mr. Lalu is doing is not good for India. But we have a twisted and perverted political system. It plays to his support base. He will get political mileage out of this in Bihar (Place were he gets elected from).
It is all about priorities. The more people move (Immigrate) within the country, the better it is for the country. It will eliminate "GETTOS". It will bring about an exchange of ideas. It will reduce caste system.
We need to have our priorities correct and hold politicians to these priorities. Today our priorities is religion, valentines day, Puja, etc. Hence these politicians manipulate the masses by playing to their sentiments.
We, the masses have to de-sensitize ourselve from these stupid issues. Water, electricity supply, road conditions, Taxes, Job opportunities need to be our priorities.
