The most common mechanism for distributing Saudi Arabia's wealth to the royal family is the formal, budgeted system of monthly stipends that members of the Al Saud family receive, according to the cable. Managed by the Ministry of Finance's "Office of Decisions and Rules," which acts like a kind of welfare office for Saudi royalty, the royal stipends in the mid-1990s ran from about $800 a month for "the lowliest member of the most remote branch of the family" to $200,000-$270,000 a month for one of the surviving sons of Abdul-Aziz Ibn Saud, the founder of modern Saudi Arabia.
Grandchildren received around $27,000 a month, "according to one contact familiar with the stipends" system, the cable says. Great-grandchildren received about $13,000 and great-great- grandchildren $8,000 a month.
"Bonus payments are available for marriage and palace building," according to the cable, which estimates that the system cost the country, which had an annual budget of $40 billion at the time, some $2 billion a year.....
In a meeting with the U.S. ambassador at the time, one Saudi prince, alluding to the off-budget programs, "lamented the travesty that revenues from 'one million barrels of oil per day' go entirely to 'five or six princes,'" according to the cable, which quoted the prince.
