If it was ancient then it was around during the Qing Empire, and it clearly didn't work for the Qing Empire. In fact, the problem was not even one of technology. In 1880s, Qing Beiyang Navy had metal battleships with steam power, artillery, electricity, etc. and still lost to Japan.
There was something new introduced by the PRC. I am not allowed to say. But you can infer for yourself.
Just because something was in use at the time of the late Qing doesn’t automatically make it trash, and just because something is new doesn’t make it not trash. Correlation doesn’t equal causation.
Indeed, the root cause of the downfall of the Qing, and all dynasties before them, is arrogance and complacency in thinking they have found the magic source code to life. This then lead to wanton corruption, cronyism and the abandonment of all of the core principles and practices that allowed them to gain power in the first place.
The worst thing a society can do is allow power to be inherited instead of earned. What inevitability happens when that happens is that insecure spoilt brats persecute and eliminate everyone with real learning, talent and capability around them as those people pose too much of a threat to their egos by having all those admirable qualities the spoilt brats can’t or won’t attain themselves. The brats then surrounded themselves with talentless and shameless yes-men cronies who’s sole purpose is to make the brats feel good about themselves.
The yes-men cronies then repeat and cascade the same effect downwards and outwards until the entire core of imperial power is rotten through.
If that sounds familiar it should, as we are seeing the late stages of such an idiot infestation play out across western capitals in real time.
In the modern western political world, talent is entirely irrelevant. The best test scores in the world doesn’t count for shit in an election, indeed, in most cases it’s an actual detriment since so much of American society at large are illiterate and gets triggered by smart people who actually applied themselves and achieved their potential. What really matters is name recognition and money. The only ‘outsiders’ who could break into this walled garden of the political elite are people like Trump, who are media whores billionaires who spent the overwhelming majority of their life and wealth name dropping themselves every chance they get to build enough name recognition to allow their money to do the rest. And even then look at what happened with the old school American political elite closing ranges to try and freeze him out of having a second term via the courts.
The best thing that the PRC has done is allow true upwards mobility of its people to move into any post in the land so long as their talent, willpower and luck holds out, in that all of the top decision making positions are earned through decades of consistent hard work and results instead of empty slogans and outright lies.
If you think that is the magic ‘cheat code’, then you are right. But the price of leading them world is eternal vigilance, hard work and humility.
China must always be willing to learn, even from countries doing not as well as itself overall, if they are doing something better than China. It must always check and root out all attempts by the powerful to corrupt the system to unfairly advantage and advance their offspring. And the Chinese as a people must always be prepared to work just as hard or harder than then competition to maintain its leading position.
America is failing because it is breaking all of these rules. It openly allows the corruption of every aspect and institution it claims to hold sacrosanct; advancement to high power is all but barred to the overwhelming majority of people without the right family and social connections; and the people itself is lazy and entitled and seeks to maintain its unfairly earned world position and power by actively sabotaging the competition instead of trying to do better themselves. How could they not be falling behind behaving like that?
This is why ‘spreading democracy’ is so important to western elites. They don’t need to do better if they corrupt the rest of the world to be worse than themselves. Just look at Jai Hindland as the living warning of what the rest of the world would be like if their perverted and corrupted version of ‘democracy’ is allowed to spread and take root.
