Here is Ali Shihabi:
In the short term, these detentions will lead, directly and indirectly (i.e., by example of what can happen to those who do not cooperate), to the recovery of substantial ill-gotten assets from many members of the elite, including, in all probability, vast tracts of urban land that were “acquired” by senior royals in decades past. The monopolization of this resource limited the amount of urban land available to the masses, pushing up land and home prices, which contributed to massive land and home shortages. Remedying this situation will reduce the cost of home ownership, thereby alleviating a major source of grievance among middle- and lower-class Saudis.
More importantly, in a country beset by an extremely wide political spectrum ranging from the extreme religious right to the liberal left, achieving consensus on key issues is virtually impossible. Hence, if any reform is to take place within a reasonable time frame, it will have to be autocratically managed. Reforms such as removing the prohibition on women’s driving, combating extremism, and curbing elite entitlements would have been impossible to accomplish through deliberation and consensus. Coercive action and an authoritarian hand, rather than endless debate, discussion, and negotiation with thousands of royals and political, economic, and religious elites, was needed to drive home to these individuals that the monarchy is serious about fundamental reform and that the “old guard” needs to get with the program or face dire consequences.
Previous attempts to negotiate elite entitlements achieved negligible results. To cite just one example, relentless pushback and delay tactics scuttled a recent initiative that would have forced elites to pay full utility costs and newly introduced property taxes on undeveloped land. Arresting high-profile household names, people long considered to be untouchable, was the best way for the King and the Crown Prince to deliver the shock needed to recalibrate the behavior and expectations of the elite class.
I am not convinced by the conclusion, but here goes:
Paradoxically, the Saudi “purge” may very well secure the future of Saudi elites as a class, and even the future of the very elites who were arrested. In Dubai, the crackdown ended when convicted elites were quietly released after they had returned looted state assets. It is probable that the Kingdom will follow a similar path. For Saudi elites, succumbing to a “revolution” from above that requires them to forfeit some of their extreme wealth and privilege is still preferable to a real populist revolution from below, which would wipe them out completely and destroy the country.
