Yes.
Better be abroad, send money to Pakistan than to be unemployed and idle in Pakistan. As for those cursing ZAB--you guys are so ignorant!! It was one of ZAB's successes that he created mechanisms to send millions of Pakistanis abroad to the Middle East. I remember Jang newspaper in the 70s and then 80s coming up with govt ads to send labor to the Middle East in an organized, vetted, and coordinated with foreign countries ways. They may have been low wages but they did and still do send billions of $$ to Pakistan. The remittance received from the overseas Pakistanis probably exceed all textile exports from Pakistan!!
So long as Pakistan has surplus labor--educated or not--it's better they are send abroad. With the West declining in fertility rates, Pakistan and other poor countries are well placed to provide the labor. It is a win-win overall, some xenophobia notwithstanding.
