My view is the “central planners” in 2001, started pushing the US Dollar lower. Because of various reasons. USA commodity prices were in 20 year bear market by 2001.
US Producers were going out of business. Remember? After George Bush Jr got in “they” had “him” put tariffs on steel and lumber. Until the lower dollar kicked in to raise the prices and help the USA live.
Obviously, by 2012, “they” must have decided the USA was replenished enough, and a stronger dollar was needed to replenish a weakening Europe Japan et all. Don’t forget, when they help the USA, the OTHERS get hurt, and vice versus.
This is all simple stuff. Like a farmer watering various areas of the farm. They started this crap after WW II. Breton Woods agreement. By late 2015, Gold at $1060 and other commodities were already in a long 4 year correction.
In the long run, the global economy NEEDS a healthy prosperous US consumer/taxpayer. The US consumer/taxpayer, does NOT need a healthy wealthy Global economy. History since 1913 has shown, they need us MORE than we need them. Simple. “They” have to build us up for their benefit later on.
