There is, however, a critical flaw in this narrative. China’s economy may fail to overtake the US as it succumbs to the proverbial middle-income trap. This is where the relative development progress of countries in relation to richer nations stalls, and is normally characterised by difficult economic adjustment and often by unpredictable political consequences.
Historically, China’s growth miracle has been remarkable. In the 30 years to 1990. The money GDP (the market value of goods and services produced in an economy) for China and the US in American dollar terms grew more or less in tandem at just over 6% and 8% per annum, respectively. . But in the next three decades, China’s GDP growth doubled to over 13%, while America’s halved to 4.5%. That pushed China’s GDP up from 5% of American GDP to 66%.
