Not sure what you mean. The Middle East is making out like bandits, it makes a sizeable percentage of the GDP in south and East Asia etc. it just feels like you’re putting Norway on a pedestal for no particular reason.
But, one wonders why a very rich society would need to resort to enslaving people in order to save a buck.
Also, I’m not sure how much has changed since I left that part of the world, but for decades the blue collar workers (Filipinos, Indians, Pakistanis, etc.) were considered lower tier class in rich Gulf countries. Probably easier to exploit those who one feels are less deserving.
