I've seen a lot of individuals like this in my life.... "I don't want to play, so the game is over". No dude, you're welcome to not participate, but you're not the life of this group.
Isn't it beatiful how none of us do or could ever matter? But why does orange man get to have such influence. No one should matter in this world, that's the point!
We (the west) helped them become who they are. We relocated all our production there because they were cheap and didn't mind throwing a bunch of poor people into the grinder. Arguably, the fastest and most efficient way for them to get out from under our thumb was authoritarian rule. Democratic rule would've been torpedoed by the US or one of its European vassals in favour of an authoritarian one we installed.
The world could've looked very different had the US not meddled in a lot of countries. Here's an entire list that probably has about 70 countries on it.
No. Just because the US has become worse than before and China didn't, even if the US closed in on how bad China is, that doesn't make China better than the US. More reliable, yes, but not better.
