A US 3% growth rate vs. China's 5% growth rate would mean it would take 2-3 decades for China to converge to US GDP levels despite China having a 4x population of the United StatesEven if you assume all US' 3% growth is healthy and not simply inflation stacking, it's still a mathematical impossibility to catch up with China, which is accelerating away at 5%+.
Only hope US has at this point of catching up with China is the ww2 German strategy I.e. annexing lands into itself lol
Trump actually has that idea with Canada but Canada alone still does not make up for the GDP gap between the 2 global major powers. Maybe try all of the EU...
