Your graph is stupid and doesn't say what you want it to say. That's consumption as a percentage of GDP. China's spending has grown faster than American spending, but its GDP has grown much much faster than American GDP. Basically, in China's situation, it's showing GDP growth so quick that consumption can't catch up, like if you already live a pretty fulfilling life but your boss keeps doubling your salary every year and you can't think of what you want to buy with the extra money. Now the US chart just shows Americans cutting deeper and deeper into their savings to spend and buy things. I can spike that chart for myself personally if I went to the mall tomorrow and maxed out my credit card with no change to my income. Guy A: earning so much money he can't spend it fast enough even though his spending is rising among the fastest in the world. Guy B: spending more and more of his income and saving less and less. And you say the first guy is the one with the problem? LOL Like I said before: you think you're an economist but you can't even read a chart...
You made a quite nice salad bowl piling up unrelated things.
Check the correlation between the negative interest rate on savings, and the decreasing consumption.
Considering that prior of 201X the Chinese household hasn't got significant debt but they had savings the negative interest rate was a transfer mechanism from the households to the banks/SOEs to recapitalise them.
They used this money first to make export capacity, second to create a huge infrastructure driven economy.
Basically, in China's situation, it's showing GDP growth so quick that consumption can't catch up, like if you already live a pretty fulfilling life but your boss keeps doubling your salary every year and you can't think of what you want to buy with the extra money.
So, you saying that the reason why the Chinese doesn't spend money because they salary growing faster than they consumption?
I think if it is the case then you can expect to see the savings of the households going up.
But if I check the above graph it showing the opposite.
The Chinese household needs loans to reach the expected level of living.
Without wasting too much time , don't you think that the three graph ( real interest rate, household share of GDP , household debt) showing a different, and very sorry story about the current state of the Chinese consumers?
So, check the second part of your reasoning, the US consumer who has to go deeper and deeper into the debt.
Now the US chart just shows Americans cutting deeper and deeper into their savings to spend and buy things.
Whops.
So, the Chinese consumer keeping his minuscule share from the GDP by taking loans like madman, and the US consumer keeping his share by saving.
I know that on the internet forums the logical thinking is not so popular, but please, can you see the issue with your chain of logic?
