The world is not better by any measure.
Strictly speaking, that's not true. The world is now aware of how painfully unprepared we are for cataclysmic events, like pandemics.
The world now also knows how dangerous China is due to the dangers of offshore supply chains, the disinformation they spread which endangered lives, and the dangerously strong influence they have over the WHO.
These are all good things and we're better off knowing them.
There is no logical link between willfully making our own government incompetent and corrupt just so we can realize how unprepared we are. That sounds like a self fulfilling prophecy.
Maybe you've known it. The people at large did not and now they do. Anti-China policy was often viewed as racist. Don't underestimate the power of common knowledge to influence the political winds.
However, I will fix it for you, zero percent of the US supports Trump or believes he has made the country a better place. There is a zero percent chance he will win the next election. Is that the delutional propoganda you prefer?
