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.
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.)

Per capita means per person. Purchasing power means real production. The question was about potential living standards, not aggregate might.
