It mentions it in the article, which technically references Lighthizer's book passage:
" ‘A crucial mistake,’ according to Lighthizer, had been to let China into the WTO and treat it as just another country like America’s free-market allies. The result was that millions of well-paid jobs in US manufacturing disappeared, as more and more work was outsourced and offshored. "
A close examination of the passage appears to be correct: accordingly, China only met about 50% of the WTO entry requirement in the last 20 years. They were in essence, acting as a bad actor. Not only that, now they were seeking, prior to covid, to replace the current rule based trading system, with one where they got to have unlimited export to other countries, while the government suppressed wages and consumer spending internally, in order to strengthen the state. All other countries production be damned. The low wage low cost export would destroy all of the production capabilities in other countries.
And now with China openly claiming to Europe that Russia must not fail, they are blatant in their desire to destroy the western democracies, in support of authoritarian dictatorships in the world.
1.) 2008 financial crisis, 67% -> 82%
2.) covid, 105% -> 125%
so basically, a one time war injury upon America's finance and health.
