This is pure bogus. Without free trade with China most of today's smartphones would simply be too expensive, in the reach of only 1% of the people (yeah, that number is taken out of my a.s, but you get the idea). With no smart-phones there would be no "unicorns", there would be less profits for FB, Google and Apple itself.

And there's also the fact that you cannot "price in" into any economic equations the improvement in life conditions brought in to the general public by the use of smart-phones.

Economics as a science needs a total re-think, or at least they should tone down their end-of-the-world statements.
