The US investing in the Chinese "pie" is useless because they're just feeding the CCP more. CCP will use the power to take over the world. US companies would get eaten by the Chinese companies and US gov would be taken over from within, once mainstream and social media is taken over by CCP hands.
But don't be afraid of China taking over US cyberspace, I wouldn't be surprised that the Anglo-Europeans will build their Hadrian fire wall. To keep the Eurasian troll armies out of their part of the cyber world. This might all grow out of the clean network initiative.
For most non westerns nothing will really change if the king sits in Washington or Beijing. If you think it does you have been drowned in US propaganda. Maybe the biggest historical difference is that Beijing builds, and Washington bombs cities in the global south.
TLDR: CCP doesn't answer to the people. US gov at least has open elections.
I agree that at this moment, a poor person in central africa should not care 1% between US and CCP. But for their descendants, yes they should care.
Taiwan's silicon shield and western semi conductor independence are contradicting objectives, sacrificing Taiwan for a bigger piece of the Chinese market is more then worth it from a realist/Mercantilism perspective.
