China's power as a global investor also benefits US
Some petty-minded people ruin their own opportunities by viewing their potential partners as being as mercantilistic as themselves. This is the way in which some trade war warriors in the United States see their country's trade relations with China.
They see China, by selling more to the US, as being cunning or pursuing the strategic goal of eventually undoing the US. They say the US, which sells less merchandise to China, is being robbed of its jobs, and claim its economy is being raped.
They refuse to see that every year China is buying a lot more services from the US, Chinese parents pay huge amounts to educate their children in US colleges, and that in more recent years, Chinese companies have begun investing more and more in US companies.
