That has already transpired.
Of course, it’s not reported on in the Western “news” media.
The subject is “China’s economy”, and since China is socialist, the measure of economy is based on the needs of the people; the citizenry. That measure is PPP. It measures the health and general well-being on the majority of citizens.
This is quite different from the “United States economy”. Since the United States is a oligarchy (though others might convincingly argue that it is a plutocracy or a kakistocracy) that masquerades as a “democracy”, the measure of the economy is based upon the needs of the richest 0.01% of the population. That measure is GDP. It measures the successful wealth of the oligarchy.
If you compare the two economies, it is a useless and worthless task. They are as different as apples and oranges.
- China serves the people. Measured success is in PPP.
- The United States serves the oligarchy. Measured success is in GDP.
Trying to measure the success of China by GDP is as worthless an indicator as trying to measure the success of the United States by PPP.
So it is useless to compare the two.
But that is not what the question asks.
The question wants to compare the strength of each nation relative to GLOBAL stature.
So let’s compare China’s PPP with the rest of the world. China is by far leading the world in this measure. By rank size and value. China dominates the world in providing the best living conditions for it’s citizenry.
And, likewise, let’s compare the United States GDP with the rest of the world. The USA is presently leading the world in providing the best environment for oligarchs to live and thrive in. No one comes close.
So the question asks about the “indicators” showing that China will surpass the United States.
In regards to PPP;
- China surpassed the United States over a decade ago in 2014.
In regards to GDP;
- China is likely to surpass the United States by the early 2030’s. Say as early as five years from now, to maybe a decade later. The reasoning has to do with the enormous size of the Chinese population, new technology and innovation; a huge and robust manufacturing economy, and careful control of its economy.
