In the Persian Gulf countries - and I assume its the same in Saudi Arabia - the high tech and technical stuff (doctors, banking, engineers, those running the infrastructure etc) were all Westerners. The shopkeepers, factory workers and construction crews and those who did the tough dirty work were from the Indian subcontinent. The Arabs didnt do much of anything except soak up government handouts.
Oil is not going to last forever and as their population grows, the benefits get less lavish anyway. If theyre not to experience a brutal crash in their living standard in the next generation or two, their own people are going to have to get off their asses and start working. Theyre going to have to admit to themselves that memorizing passages in a 1300 year old book is not education and does nothing to prepare one for the modern world.
