That move from China is aimed at undermining this ability. I'm completely not rooting for the Chinese, but the risk is real. If they succeed, the US will need to cut internal consumption by 2.6%, which will hit heavily an already struggling middle class. Not a good prospect.
But. (There's always a but.) I'm not disputing that the US isn't a great economic powerhouse. What I'm getting at is, at what cost.
If the middle-class gets gutted and relative and absolute poverty keeps increasing then we're not really creating a just society, are we? In one of the wealthiest, if not the wealthiest nation ever if we still haven't figured out how to protect the most vulnerable among us then we've a bit of a problem. As some have suggested, maybe basic income is a solution? But to others you may as well have suggested that that dude Stalin may have made a nice omelette even though he broke a few eggs.
And outside the US, what the untenable situation where two countries (neither of which are the US) have to trade oil in dollars. For just how long do you think that arrangement will last? It could be, and has been, argued that some part of the might of the US comes from having its currency as the world currency and part of that is dollar-denominated trade. Cease that and the landscape alters. China knows that. Others know that.

The us has been coasting on good will and trump is squandering it. Now that he world doesn't see the us as a reliable partner, we're going to see the rug pulled out from under us rather quickly. China right now looks like a safer bet if you're looking for an ally.
