China benefited greatly from the US-led globalism order that's been going on since WWII.

Another way of saying it is China took the most advantage. And it has gone way overboard in taking advantage. So the backlash is expected and necessary.

Part of fixing things involve doing things that seem like it's destroying the order that the US created itself.

Labour laws, for starters.

The conditions the average Chinese works in are abysmal, even from the American point of view.

Well, then you basically know what to do. Rescind those laws and become competitive again.
