"It was the only option left to them after they experienced rampant corruption in the education, justice and bureaucratic systems of India". This I doubt, most of them are going abroad just under the delusion that GRASS IS GREENER ON THE OTHER SIDE or herd mentality looking at some senior of theirs from the college going there. But my interaction with many of them abroad tells me that 70-80% of them face difficulties in coping up but stay put to make dollars! No thought of corruption here, just dollars, I bet the same NRIs will come back tomorrow, if the private sector will stary paying high, even if we have the same corruption in India.
