Yeah testing for now, I know. But that's just testing for eventual launch. China WILL launch this draconian digital currency that's an eventuality. It's designed to achieve the ultimate goal that the Chinese government wants to achieve: Control of the world.
If the corrupt officials want to skip the country with stolen billions, they will still do so, digital currency or no digital currency. This digital currency is created by the Chinese government. You don't think they will create some kind of "backdoor" to benefit high officials of the Chinese government in some way? In countries like China, the government is never at the same level as the people; they are always above the people. They are never the public servants like in the West; they are the public boss. This digital currency is created to control the Chinese people and the people in the rest of the world, not the Chinese government itself. Make no mistake about it.
You're mixing too many things...
1. Digital currency: it's a system that democracies and dictatorships will use. No, there will be no way for corrupt officials and corporate executives to flee with digital currency unless it is hacked (which it will be until it becomes very difficult to do). In a dictatorship, government can do whatever it wants to do, give and take, and doesn't need a backdoor.
2. As we agree, China is a dictatorship and government serves the people as they see fit, like all dictatorships. Ask Russians, North Korean, Cubans, Venezuelans, Saudis, Iranian and so many other dictatorships of all political or religious spectrums. All they have in common is a desire for strict order.
Chinese culture itself is highly hierarchical. From the lowest to the highest level of society there's a hierarchy that cannot be disrespected unless one has the skills, guts, character and/or support to challenge the next level of authority. Chinese people are known to protest and risk their lives to challenge the system, like in Hong Kong and many other regions of China, but most Chinese support their government for having taken them out of 18th century poverty and brought them to 21st century comfort and consumption.
Yes, the Chinese communist party is obsessed with control. As a nation, China is very young and came to be thanks to the CCP. It is fighting internally to preserve its unity, it is fighting politically to validate the communist ideology, it is fighting internationally to be recognized as a leading superpower.
Like all leading powers before them, they don't plead to sit at the big table, they demand. We westerners have only every seen westerners lead and direct and decide for all how things shall be. The Chinese are telling us that era is over and frankly, I don't disagree with the premise. We western powers need to make room for China, not as a minority consolation prize, but as a nation that has demonstrated their capabilities and their ability to challenge any nation. In turn, they need to learn what the democratic process is, what diversity of ideas means and what groups of nations have already established as various fundamental rights. I'm convinced the Chinese people are eager to learn, just not under threat or punishment for questioning what is established.
