However, the standard of living in China has not reached the level of Western democracies. At the same time, it is more likely that the standard of living of ordinary citizens of the China will never reach the standard of living of citizens of countries with a more democratic form of government.
There is one important economic law - the standard of living in democratic countries is always higher than in totalitarian ones. There are exceptions to this rule, but they only confirm this rule...
I disagree mainly because you are comparing apples with apples with a different color. Democracy is dictatorship with a different face. But also the evidence suggests otherwise. If you want to compare, you have to compare countries based on their own situation (geography, population,etc.) and over time.
China is a country that has been harmed by the colonizers and with the wars forced on them, their country and people were in ruins. Over the past 40 years for example, China has eradicated absolute poverty that 85% of its population were struggling with. That is 800 million people living in absolute poverty at the time. Over the same time they expanded their economy, built massive industries and turned into the second biggest and strongest economy, all from nothing!
Note that I'm not defending dictatorships here but that we haven't seen any good results from democracies in comparison. What have the "democratic" countries done in the same period? The poverty rate has been growing and homeless people are filling the streets. Middle class no longer has the same meaning since it is now what lower class used to be! Everywhere you look people are protesting against their "democratically elected regimes" for the increasing cost of living and generally the injustice, like in France where the protests reached their 5th consecutive year. And it's only getting worse.
I don't know what you call high standard of living but if you have to borrow money to be able to live in heavy debt all your life and if you get sick you have to declare bankruptcy the next day in a country where a 6-year old is arrested for intentionally shooting someone else (6000+ kids per year!), I would not even call it a living.
In my opinion, China has made progress in economic development due to its adequate and pragmatic policies.
The leaders of China first cooperated with the leadership of the USSR, then with Western democracies. China has become the world's factory through cooperation with the United States. At the same time, he himself actively explored Africa, buying up promising enterprises there.
However, China has not been able to offer the world anything similar to Western liberal values (which are indeed of great value).
Strictly speaking, when Russia followed the path of Western democracies (2000-2014), it was a fairly comfortable place to live.
At least then people did not flee from Russia to Kazakhstan, Kyrgyzstan, Georgia, Armenia, Turkey and Mongolia.
Trade may be boring, but it promotes economic growth....
Respect for human rights may be associated with a developed bureaucracy, but you are sure that you will not become a victim of repression....
