It's not a uniquely Western trend to want freedom, voting rights, and justice. It's also not uniquely Western to see the regime party members get super rich and get angry.
But I think you're underestimating the extent to which universalism is a Western metacognitive bias that other cultures don't necessarily share [1].
The idea that there is one universal set of rules that everyone in the world can and should agree on, based on logic and rational consideration, is not really shared by all other cultures.
The Chinese response that 'it may work for the West, but it's not for us', is not a specious cop-out (the Western response being typically what do you mean there are two sets of rules!?) but probably represents the honest opinion of a large fraction of the population.
That's even before we get to the end result of democratic elections in many countries, where dictators are who the people choose.
