Well, you tell which came first - chicken or egg ? Someone got to make the sacrifice at the begining for well being of future generations. If one go by your theory, we will never make any development. SEZ's are great opportunity to a country, and brings in innovations and employment for millions. As you say, there will be corrupt politicians who take advantage of such siutations, but atleast we are not a stagnant economy (I do not justify corruption, but its a contagious system we have to live with).
