Because keeping a large diverse country stable and safe is very difficult, and a failure causes enormous tragedy. The approach that works to keep the US stable does not always work well in other countries. To keep the billion people who live in China safe from civil war and rampant terrorism is already a great achievement -- even it comes at the expense of some nice things such as human rights. In fact, China manages…
I always am humbled to think about the many massive wars in China that no one in the West has ever heard of—for example, the Punti Hakka Clan Wars in the 19th century which killed a million people, which is around the same number that died in the US Civil War. Similarly, in one year, 1858, the amount of opium imported into China was the same as the entire production for the decade around 2010. And in the Great Leap F…
In the earlier years, CCP was responsible for some of the worst suffering that the 20th century has seen; worse, it was totally without purpose. It was not even helping some people survive at the expense of others, it was just destroying millions of lives to satisfy the egos and delusions of a few leaders who were especially good at brainwashing people. Those leaders deserve to burn in hell for eternity, in my opinion.
Today's CCP, despite the continuity in the government, is very far from doing that. Of course, it wants to stay in power, as almost every government does. But I do not know whether, in staying in power, it's also helping hold back the gates of death or suffering.
As you say, the evidence so far, limited as it is, is slightly positive. China moved from one of the poorest large countries, with a horrible past, to a place where many (although not all) people are happy to return after they travelled the world.
But in truth, we'll never know for sure, since we can't see the alternate timeline of history. In a few decades, we'll merely have a bit more evidence one way or the other.
However, I do see a lot of moderate to terrible disasters that befall other countries that try to change their system of government. So I personally have a very high degree of concern about the risk that comes with such changes.
