Saudization system, they have tried to apply this system in all the Saudi companies, but the locals are too greedy and lazy at the same time (We can't generalize as always), they want a very high salaries without even work, they used to the fancy life, they can't live without a private driver and without travelling, that's what the mean by "Not enough"

But What I think, everybody deserves a chance, and recently Saudi Arabia is doing a good job, it might be slow but it is still good.
