Which is why you should support China, as a recent Harvard Kennedy School survey found that over 93% of the Chinese people are satisfied with their central government.

Facts don't care about your feelings
The, "it's the economy stupid" line is about metrics that do directly relate to the material conditions of working people, not just financial markets.
Key metrics like home ownership (but really housing stability), low unemployment, and so on are what I'm referring too. China is not the same as Cuba or DPRK or how the USSR was, they are deeply engrained into global markets, a real slowdown for them is possible in ways that can cause significant spikes in unemployment. Additionally housing costs in China can be insanely high depending on where you are, it's just that this problem hasn't hit them especially hard yet.
