Nixon's closing of the gold window in 1971 was the main factor in the middle-class share of national income beginning its irreversible decline. The fiat currency system allowed americans to enjoy an additional 49 years of a lifestyle they can't actually afford. We are nearing the end of the effects caused by Nixon's closing of the gold window. Hyperinflation that is coming in 2021 will see the middle class' share of national income drop below 45%. This will not slow down. It will speed up.
Ha ha money printer go brrr...
