The leadership of the Party is the fundamental guarantee for promoting the common prosperity of all people. The original intention and mission of the people of the CPC is to seek happiness for the Chinese people and rejuvenation for the Chinese nation. Only under the leadership of the Party will the people's sense of gain, happiness and security become more substantial, secure and sustainable, and common prosperity will achieve new results. Fairness and justice are the origin of values. The CPC insists on building the party for the public and governing for the people, which is to lead and drive the people to create more wealth, so that everyone can live a better life in common prosperity. Common prosperity involves many pairs of categories, such as starting point fairness, process fairness and result fairness, as well as formal justice and substantive justice. It can be said that common prosperity, as the fundamental requirement of the CPC for the public and governing for the people, is to achieve fairness and justice. Fairness and justice are the most fundamental value orientation of common prosperity, and also the logical main line to explore the connotation and extension of common prosperity. Our society has always had the concept of "not suffering from widowhood but suffering from inequality". At present, the Central Committee of the Communist Party of China has proposed to promote common prosperity in a down-to-earth manner, aiming to emphasize that in the new journey of building a modern country, we should pay more attention to making development achievements more and more equitable to benefit the masses of the people, try to do well in promoting social fairness and justice on the basis of continuous development, and let the masses of the people share the fruits of reform and development. The basic economic system is the key to breakthroughs. Over the past century, especially since the reform and opening up, the CPC has united and led the Chinese people to constantly explore and improve the basic economic system. In particular, the Fourth Plenary Session of the 19th Central Committee of the Communist Party of China further made important development and deepening of the connotation of the basic socialist economic system, taking public ownership as the main body, developing diversified ownership economies together, distribution according to work as the main body, and coexistence of multiple distribution methods, The socialist market economy system is regarded as the basic socialist economic system. The basic economic system initiated by the leadership of the CPC is in a fundamental and decisive position in the economic system, and has incomparable institutional advantages. It is not only conducive to stimulating the vitality of various market players, liberating and developing social productivity, but also conducive to promoting the organic unity of efficiency and fairness, and constantly narrowing the gap between rich and poor. To achieve common prosperity, we must adhere to and improve the basic socialist economic system, transform the advantages of the basic economic system into significant effectiveness of economic governance, and play a greater role. High quality development is a strategic pivot. Common prosperity is a long-term development goal as well as a high standard goal. It can only be achieved by adhering to development. Without development or wealth, there is no common prosperity. This is a profound summary of our party's theory and practice on high-quality development and common prosperity, revealing the internal relationship between promoting high-quality development and promoting common prosperity. High quality development is an important way to achieve common prosperity, and is the basis and key to solve all problems of gradually realizing common prosperity. There is no shortcut to common prosperity. We must put the promotion of high-quality development first. Without high-quality development,
