> Comparing a 10 year US period to a 20 year period? Seems awfully selective
Yes, I chose the strongest form of the other side’s argument to show that even then, it’s difficult to argue that Chinese PPP GDP/c is approaching American levels within a generation. (Though China’s numbers don’t vary much between 10 and 20 years, America’s do since we had a lot of war and then economic stimulus in the 2000s.)

You want to make multi-decade projections off a pandemic baseline?
> 4x the number of people, but 0.5x the GDP growth
Per capita means per person. Purchasing power means real production. The question was about potential living standards, not aggregate might.
Let's do a side by side comparison? 2018 to 2023? 2023 is the last year with solid numbers.
US: 12% real GDP growth
China: 26% real GDP growth
Sounds impressive, until you account for the base.
US: +$2.4T USD
China: +$3.64T USD
Yikes! 4x the number of people, but 0.5x the GDP growth.
