What happened in 1971 is more than just that single year but 1971 was the start of a major shift in world economics that included the formation of OPEC I would also be surprised if many people even know what OPEC is beyond the simplistic narration seen on the news when OPEC raises or lowers production As to your final point about reduced investment in oil, this is really a shock?
