In reality, there's two separate economies within the PRC. Around 40% live in the modern world we see in images of China (skyscrapers, EVs, high-speed trains, etc.). Awesome stuff, to be sure, and that same environment has been engineered to track every single interaction you make with it. You must use Wechat; no exceptions. Say the wrong thing on the Internet? You might lose the ability to take long-distance train or airplane rides within China, let alone international travel rights.
The other 60% live with dirt floors, hand carts, and engage primarily in subsistence farming. (It's been about five years since I last looked up those stats, but it should be around the same.) The US has eliminated this level of poverty; having even access to an automobile is enough.
The PRC argues they're able to take care of all their people, but they're nowhere near out of the woods when it comes to food insecurity. Due to population and geographic realities, they simply cannot grow enough food to feed their own people, so importation is an absolute necessity. For this reason, "unlicensed" fishing fleets (no Chinese group larger than 20 people operates without de-facto government consent) sail across oceans to fish just outside a country's territorial waters.
The Chinese political economy appears to be rationalist, but few countries have more political dishonesty than the PRC. According to an old friend who extensively knows Chinese politics, there's three main political factions: pro-Xi reformers, anti-Xi old guard Communists, and everyone else. Their ability to disappear a political enemy without what we'd term "due process" is truly unheard of in the West. Local politics is arguably worse; bribery is how anything gets done, and local officials suppress incident fatalities because over a certain threshold (around 30), the higher-ups will shame them. In such a media-controlled environment, that's less difficult than you might think living in the West.
When you talk about exporting wealth with EVs, that comes with the understanding that the PRC has de-facto control of your vehicle. Most people dislike the idea of the PRC not only retaining all data gathered by your car but having remote access to disable or drive it. If that's alright with you, go right ahead.
