improving the country for the people
Also, Zeihan overselling or not, China is facing an unprecedented demographic decline. So to the parent comment about "not doing anything and winning", honestly the US can do the same and watch China implode demographically.
Also, the CCP ultimately derives its legitimacy from materially improving the country for the Chinese people: back in the day fighting back against the Japanese and corrupt warlords, now economic progress. Both the Chinese people and the CCP know well what it means if they stop delivering and the "Mandate of Heaven" expires.

China's demographic decline will take decades and unless the CCP really fucks things up (eg. invading Taiwan and failing miserably at it), it's going to be a Japan/Korea-style slow-motion stagnation, not a dramatic implosion.
The real change is that the US economy isn't obviously superior to the next however many economies combined. Consequently the US is losing the ability to impose its opinions on others as fundamental truths. It looks like everyone in the West will have to re-learn negotiation and it'll probably be a rocky process.
Meanwhile, China has been getting better and better, looking at US as an example, and correctly avoiding providing the "freedoms" given to us in US in avoiding the same fate.
