Let's do the arithmetic. Let's say that everyone's consumption goes up by two units.
That means, for the U.S.:
329,000,000 x 2 = 658,000,000 additional units consumed.
And for China, it means:
1,394,200,000 x 2 = 2,788,400,000 additional units consumed
In other words, any change in consumption rate is going to have more than four times the impact coming from China than coming from the U.S., because China has more than four times the population of the U.S.
As I said, simple math:
population x rate of consumption = total consumption
it's not one or the other. It's both.
That means, for the U.S.:
329,000,000 x 2 = 658,000,000 additional units consumed.
And for China, it means:
1,394,200,000 x 2 = 2,788,400,000 additional units consumed
In other words, any change in consumption rate is going to have more than four times the impact coming from China than coming from the U.S., because China has more than four times the population of the U.S.
