You live in poor living conditions than most of North Eastern states. Per capita GDP is simply GDP / population. It is not an indicator of living condition. Piss poor will be an average BDeshi who have no modes of travel, or better hospitals around that they come to India in scores for treatment and what not. If BD was land of milk and honey why you guys come here legally and illegally in scores?
GDP per capita of Punjab is similar to BD but living condition is far better. GDP per capita of Maharashtra is higher than TN, the living conditions is better in TN. So your argument that North East are piss poor is moot.
Coming to India through barbed fence is easy. But to make them leave is lengthy process.
I was simply saying, if they can come here like this, why not go back the same way?
