Objective here is subjective. From the point of view of the CCP I’m sure everything is going swimmingly.

Existence of "point of view" does not make it subjective. You can think the moon is made of Swiss cheese, that doesn't make its composition subjective, it just makes you wrong.

Yeah, I’m fairly certain that does not apply to ‘Is my country doing well’, since the measures used are human defined.

If you put zero value on personal freedom (which isn’t objectively better, that’s just pure opinion) the equation changes.

Criteria like "not starving", "not being murdered", "not being raped", "not being put into concentration camp for following your own religion", "not being imprisoned for criticizing the government" is pretty objective, and I have yet to see a culture where being raped and murdered is praised and desired by people. I am sure whatever are the cultural differences in China, they like starvation, rape, murder and imprisonment as little as we do. So the country which does such things to its citizens, massively, is not "doing well", even if its citizens aren't allowed to say so aloud (and that's another sign it's not doing well - "I can't complain" can mean two things, and in China it means you'd be in prison if you do).
