Well, this is a structure that results from rewarding exceptional talent/ability and contribution. It is inevitable that we move in this direction in order to cultivate innovation and growth. No country in the world can be cutting edge while favoring mediocrity, inflating the blue collar share of the pie at the expense of those who innovate and create. These are force multipliers while workers are linear contributors. Force multipliers must be favored in order to cultivate and attract them because a society that is too heavy on linear workers moves too slowly to be competitive. That is why it's more noble to be an entepreneur/innovator than it is to be a worker; it is the same all over the world.
Your view needs to evolve to fit the new times. They are old-school, the attitude that you have is what prevailed in China when China was just a large North Korea. To open a business was evil greed and that caused China to stagnate for decades. Now, to be a modern competitor, China has evolved how it thinks and how its society is structured and rewarded.
The standard of living for everyone in China, most notably the poor (via the poverty eradication drive) has improved substantially and continues to do so. Having more people get rich is only a problem if they are getting rich by making others poor; China's rich are not strengthening due to wealth redistribution favoring them and robbing the working class but because everyone is getting richer, just that the rich are doing it faster. They are doing it in due to incredibily fast wealth generation instead that has no negative effect on the blue collar class.
You mean a decline in traditional old school communism? That had to happen because that system didn't work; China had to evolve it into China's modern system and that's not a decline. China's progress in economics, technology and military are all undeniably the fastest in the world and growth of hard power is what matters. As long as that is being delivered, my support of the CCP will be unwavering.
