That is an idiotic statement by the author. If they just read Trump's books, or followed his business dealings they would know he is a master at win-win negotiation.
And when it comes to business you either win or your lose. The other guy may also win or lose. But the only deals worth having are the ones where you are winning. If the other party wins also that is a bonus.
Having a trade deal with another nation where the USA loses is never smart.

For Wall St, et al, and guys like the author it is, because they have the money invested in China.
