it is a very good article. i was born in rajasthan, brought up, educated in bengal, worked initially in bengal, then in UP, Delhi and MP. anyone in the country is free to go and work anywhere except unfortunately to north east (as rightly mentioned in the article). marathis, marwaris, gujratis, punjabis, bengalis, keralites, oriya, tamilians etc r working in different states.
the main problem is population explosion in the country, which is eating up all our limited resources, extinting many animals, birds and plants and increasing global warming. Lalu is one of the biggest culprits having about 12 children.
like china we also must forcefully enforce the rule of one child per couple. However the central govt is silent in this regard.
