I have large extended family in the gulf and they seem to fall in the following groups which I believe is representative of the overall Pakistani population in the Gulf:
1. Low skilled non labor: education levels are not very high but good enough to be working basic admin jobs. They are very happy to be in the gulf even though working conditions are difficult and basic rights are missing. They are content to save money and return to Pakistan one day.
2. Professional designations (Doc, eng, accountant, lawyer, pharmacist, etc): making good money but also realize that one day they have to leave so trying to immigrate to Canada/Australia/UK.
3. Professionals born and raised in Gulf: they don't want to leave and are delaying it as much as possible but ultimately many of them will make decisions to immigrate to the west. They were raised in the Gulf so "feel" Saudi/Emirati/Kuwaiti/etc and have a strong love for the country.
4. Older professionals: our parents generation who realize it's too late to immigrate to the west so they encourage their children to do so but stay put in the Gulf until retirement. Then they usually head back to Pakistan afterwards.
5. Professionals with religious motivation: i have one segment of the family where they are all doctors and accountants in Saudia (moved in the last 5 years). While initially they moved for better opportunities, now they have drank the kool aid and believe Saudia is the best country in the world in all aspects. They hate the west, Pakistan, other Gulf countries and believe everyone is deviant except for Saudi society. While I admire their commitment to learning the religion (as we all should), the blind love for Saudi society, monarchy, and the land in general will one day burst when reality of deportation comes calling.
I don't have any family members are direct laborers but in my direct interaction with them in the Gulf, they weren't as happy as everyone thinks they are. Many complained about long hours (12 to 14 everyday) with one or two days off per month. No leave of absence to visit families for 2-3 years and not enough pay to bring families over.
