I'm going to give you a serious answer even though it's obvious you know nothing about us and don't care to learn.
Accellerationism is stupid and reactionary, and from my perspective Biden seems to be doing a fine job of doing that as it is. Trump is a symptom produced from the policies Biden has spent his entire career enacting. There will be plenty more candidates like Trump, because the material conditions that produced him still exist, and Biden is perpetuating and worsening those conditions.
The US is in decline and that's not going to change regardless of who wins this election. What I'd most prefer is to refocus our efforts domestically in order to address some of the many different crises that the country is experiencing. If we did this, it's likely that China would eventually eclipse the US due to it's manufacturing capacity, but the lives of everyday people would be improved and the country would become more stable and healthy. Whether the decline could be reversed, I don't know, but it would at least be a gradual, peaceful decline.
But that's never going to happen, even a little bit. Instead, our leaders are intent on getting involved in conflicts all over the world while ignoring all the problems at home and allowing things to get worse and worse. The geopolitical interests of the US government are completely disconnected from the interests of the American people.
The US doesn't need to collapse for China to grow. China's strategy for many years has been a policy of peaceful coexistence with capitalist states while it focuses on economic development. And that strategy is proving successful. The only concern is what the US is going to do once it becomes eclipsed as global hegemon, and the concerning thing is that while China manufactures more than the next 10 countries combined, the US spends more on the military than the next 10 countries combined. The possibility that the US could start WWIII in an attempt to maintain hegemony by pressing the area where it has an advantage is deeply concerning.
Even if you believe, as you probably do, that Xi Jinping is paying me to run around some niche corner of the internet pretending to be Phoenix Wright - why would China actually want to destabilize the US? They're already winning the peace.
