Problem is, they can’t change their society quickly. They have an entitled “royal” class, plus their regular citizens are used to importing non-Saudis to do the actual work in the Kingdom.
Making Saudis actually willing to get their hands dirty will be a big job.
According to other posts a number of the arrested royals are experiencing real torture first hand (the sort that leaves no marks on faces and other exposed skin). They are no longer “entitled” and the whole importing of outside labor thing may go away, since the former royals will no longer have the funds they once had - funds and estates have been confiscated {this includes Al-Waleed bin Talal bin Abdulaziz al Saud} - to employ slave labor.
A little real torture has a way of encouraging one to get with the program and get one’s hands dirty.
