Looking at your comments, Mr. Kumar, it looks like you know more about tamilians and their culture than the people of tamil nadu themselves... also you say drought in tamil nadu is much worse... so being a non-south Indian you know a lot about Tamil Nadu.. I appreciate your interest in tamil nadu... though your hometown might have lot of itz own problems(if you are truly not from tamil nadu... look at my 2 points which is not generated of my own, but globally know and you can check with any government or any media news papers..
1) 562 tmc to Tamil Nadu versus 175 tmc to Tamil Nadu(source.. this article itself) 2) 3 crops per year by tamil nadu versus 2 crops by karnataka
if itz false i would accept whatever you say(check about the truth of these points anywhere)..... after finding these 2 facts are true, if you still think itz unfair.. then go to school and educate yourself and come out of narrow mindedness
