With several eastern European countries trending in an authoritarian direction (and Turkey pretty far along that path already) I am worried about the effect that Chinese prosperity without democratic ideals will have.
You can question the methodology, but then you have to make an argument as to why Norway, New Zealand, Finland, Switzerland, the United Kingdom, Denmark, the US and other mature social democracies which routinely top these rankings are not good places to live. Very few citizens of those countries would choose to live in Xi's China instead.
I only have to make the argument that personal freedom is not as important as economic prosperity. Since the end of the Cold War the general thinking was "democratic ideals -> economic prosperity -> good life". China's economic success without embracing democratic ideals to the extent that successful Western countries is making people and governments once again question whether or not the democratic ideals are actually needed.
I would rather live in the US or Europe than China at the moment, but how long will that remain true for most people if China surpasses the US as the world's reigning superpower?
But that's not the relevant question. The relevant question is whether the businesses of those countries would choose to do business from within Xi's China.
China has massively westernized and expanded its freedoms.
Sure, it still had a long way to go, but at least these days the Chinese government isn't arresting professors en mass and forcing them to work on farms.
Yes, this literally happened. It was called the cultural revolution.
As bad as humans rights and freedoms are in China, I think people really underestimate just how much worse they used to be.
There is a still a gulf between China's view of personal freedom and the West's view. It's also reasonable to be concerned that they will be moving away from the West's democratic ideals in the near future, seeing as their President just claimed the power to govern for life.
The question is whether or not they will always be playing catch up, and whether or not that's directly related to the personal freedom of their citizens.
Now to be clear, I'm obviously not advocating human rights violations, and strict governmental control ... I'm only pointing out that things like 'freedom of speech', while awesome and right IMO _may_ not exactly be the root cause of this age of prosperity.
