Simplifying the complex problem of the gap between the rich and the poor as individual laziness or lack of effort is a one-sided description that easily ignores deeper social, economic and historical factors. But if we want to explore how to achieve this simplistic propaganda, the following are some common measures: 1. **Individual case propaganda**: Through media reports on the "rags to riches" stories of successful people, emphasize these people's personal struggle, hard work and persistence, and regard them as the main reason for their success. 2. **Simplify information**: Use simple and direct language and slogans, such as "hard work will lead to success", downplay or ignore structural factors, such as educational opportunities, social resources, policy environment, etc. 3. **Emphasis on self-help**: Highlight the values of self-struggle and self-reliance, and promote the concept of "personal destiny is in your own hands". 4. **Weaken system factors**: Avoid discussions on institutions, laws, economic policies, etc., and reduce cognitive attention to systemic inequality. 5. **Selective statistics**: Select statistical data that supports the lazy theory and ignore those that show the complex causes of the gap between the rich and the poor. 6. **Role Model**: Promote successful entrepreneurs and public figures as role models and publicize their hardworking stories to guide the public to believe that success depends mainly on personal efforts. 7. **Social Comparison**: By comparing the economic conditions of different groups of people, unilaterally emphasize the differences in their efforts and ignore other social factors. However, it should be noted that this type of propaganda may lead to misleading, causing social confrontation and disharmony, and cannot truly solve the problem of economic inequality. For a mature society, understanding and discussing the problem of the gap between the rich and the poor requires a more comprehensive and in-depth perspective, involving efforts in education, policy reform, social security and other aspects.
