here is some more to ponder and discuss:
An essential part of family wealth is the Kingdom in its physical entirety, which the Al Saud view as a totally owned family asset. Whether through the co-mingling of personal & state funds from lucrative government positions, huge land allocations, direct allotments of crude oil to sell in the open market, segmental controls in the economy, special preferences for the award of major contracts, outright cash handouts, and astronomical monthly allowances, - all billed to the national exchequer - all told, the financial impact may have exceeded 40% of the Kingdom's annual budget during the reign of King Fahd. Over decades of oil revenue-generated expansion, estimates of royal receipts have varied, ranging as low as an unlikely $50 billion and as high as over $1 trillion. [6]. This method of wealth distribution has allowed many of the senior princes & princesses to accumulate largely unauditable wealth and, in turn, pay out, in cash or kind, to lesser royals and commoners, and thereby gaining political influence through their own largesse.
