The chart below shows the US 25-54yr/old population change (yoy on quarterly basis) against the same data as above. Population growth, which drives somewhere from 50% to 75% of all GDP growth, began decelerating in 1986, turned negative in 2008, bounced but has again fallen to zero as of Q1 2017 (rationale for the deceleration is discussed HERE).
And if we broaden out to the annual growth of the much larger 15-64yr/old US population...its growth has decelerated to perhaps the slowest in the last century. And against the lack of growth, household net worth as a % of disposable income hits a new record high. The Fed is using its policy "tools" to falsely engineer financially what is not there fundamentally.
