It’s the percent that is important. Looking at that chart you sent, manufacturing as a percentage of GDP has dropped from 16-10%. Total growth is irrelevant: growth from 1,400 billion to 2,400 billion between 1998 and 2021 is less than even the inflation numbers published as CPI, which we all know drastically underestimate real inflation. “Growth” that matches or lags inflation is not growth at all. If purchasing power has not grown, growth is fictitious.
