Admittedly with major problems:

Saudi Arabia is in desperate need of comprehensive political, economic, social, legal and educational reform. The economy is faltering badly, which in turn has meant that the kingdom can no longer afford the profligate ways of the royal family or the cradle-to-grave social welfare system erected during the fat years of the 1970's and 80's. The Saudi educational system is useless, emphasizing the humanities and Islamic studies at the expense of science and mathematics. Because of its reliance on rote memorization, even college graduates have few marketable job skills. Saudi Arabia's decrepit legal system is distorted by xenophobic strictures, like laws limiting foreign investment, and is undermined by abuses by the royal family.

As you see they are unqualified to fill the jobs given to foreigners
