When Nixon ended the gold-basis of the dollar and then in 1974 secretly switched to the current oil-basis, this transformation of the dollar’s backing, from gold to oil, was intended to enable the debt-financing (as opposed to the tax-financing, which is less acceptable to voters) of whatever military expenditure would be necessary in order to satisfy the profit-needs of Lockheed Corporation and of the other US manufacturers whose only markets are the US Government and its allied governments, as well as of US extractive industries such as oil and mining firms, which rely heavily upon access to foreign natural resources, as well as of Wall Street and its need for selling debt and keeping interest-rates down (and stock-prices — and therefore aristocrats’ wealth — high and rtising). This 1974 secret agreement between Nixon and King Saud lasts to the present day, and has worked well for both aristocracies. It met the needs of the very same “military-industrial complex” (the big US Government contractors) that the prior Republican President, Dwight Eisenhower, had warned might take control of US foreign policies. As Bloomberg’s Andrea Wong on 30 May 2016 explained the Nixon system that replaced the FDR system, “The basic framework was strikingly simple. The US would buy oil from Saudi Arabia and provide the kingdom military aid and equipment. In return, the Saudis would plow billions of their petrodollar revenue back into Treasuries and finance America’s spending.”
This new system didn’t only supply a constant flow of Saudi tax-money to the US Government; it supplied a constant flow of new sales-orders and profits to the military firms that were increasingly coming to control the US Government — for the benefit of both aristocracies: the Sauds, and America’s billionaires.
