The same for Saudi, they have over 46% of the population are foreigners.
Arabs have a lot of land, lots of money and not enough workers to maintain their quality of life.

It's basically apartheid were the citizens are 1st class citizens and everyone else are 2nd class. It works pretty well, specially because they don't normally charge income taxes.

They copied that model from the golden age of europe and since they're not white, they can do it freely.
