though not all... for many people the reason for moving out of country is because of the reduced opportunities(due to reservations) out of the meager opportunities available in the country... you would understand it if you look at the whole or if you go through it... it is easy to commen than go through it... even today many people have no choice but to leave(even though life in the country is better than outside) bcoz everyone cant fight for a piece of bread where 70% is reserved...
