Saudi advise to Pakistan

Have you been to the gulf yourself? I never heard of Arabs mistreating Pakistanis EVER. In UAE, Pakistanis are preferred over other South Asians. When they find out you are a Pakistani, they usually hug you like a true muslim brother. If they are that bad, why Pakistanis love to go and work in Arabia? why are they more advanced and educated than India, Russia and China- all of the countries that have lot of resources.
