Between 1995 and 2000 the GDP grew from 2% p.a towards 4.8% p.a ( 2.8% p.a change) at the same time the savings rate dropped from 4% to 2% ( 2 % change).
Between 2002 and 2006 Q4 the GDP grew from a 0.35% p.a towards 3.00 % p.a growth rate ( 2.65 % p.a change). The savings rate during that period dropped from 2.8% to a negative -1.2% . ( 4.00% change)

Most definitions of “savings” I’ve seen only include cash savings - like bank savings accounts - and not other forms like stock investments (direct or in mutual funds) or other forms of investments.

But overall, I’ve yet to see a comprehensive analysis of average savings that included investment wealth.

Every great empire reaches a peak and declines. Happened to the Greeks, Romans and British. Every month the US sends 65 billion to China who then turn around and invest it in the US. One day you’ll wake up and it won’t be made in China. It’ll be owned by China.
