This is the old deal about “purchasing-power parity” It’s not that China’s economy is really bigger than the U.S., it’s that they can buy that Starbucks coffee cheaper so their money counts for more.
Of course they have three times as many people too, but that’s not figured in either.
RE: Of course they have three times as many people too
Make that over 4 times America’s population.
US Population 316.1 Million
China Population: 1.35 Billion
