Ever since President Richard Nixon unceremoniously withdrew the U.S. from the Bretton Woods international monetary agreement in 1971, effectively ending the Gold Exchange Standard, many experts, economists and conspiracy theorists have speculated on the role that Western governments and central banks have played in suppressing the price of gold. According to Dutch economist Jaco Schipper, the memoirs of Dr. Jelle Zijlstra offer further evidence of a gold price suppression scheme carried out by Western central banks.
Dr. Jelle Zijlstra was a highly regarded politician and economist in The Netherlands from the mid-1960s through the early 1980s. During this time he held political positions including those of Senator and Minister of Economic Affairs. In 1966 Zijlstra became Prime Minister and also held the position of Finance Minister.
