The CCP is super clever and imbued a sort of nationalistic pride from birth. Instead of the US's more complicated dualistic individualism/patriotism combo, the Chinese people actually get some sort of pride for being a cog in the CCP machine.
It's a completely different paradigm and obviously super dangerous because it allows the people at the top who aren't elected to pull the strings on a machine of 1.4 billion people. If they run the system correctly, it can be much more "effective".
Democracy has lots of pressure outlets, and it is definitely much more healthy longterm. That's why I think it's the better system, even vs a well-run (and let's even assume benevolent) CCP.
