I can speculate on the hypothetical scenario you mentioned. If the world were all rich and peaceful, it would likely be a place where there is an abundance of resources and minimal conflict or violence. Such a world could potentially lead to increased happiness and well-being for many people, as basic needs would be readily met, and there would be fewer causes of stress and suffering.
In a world where everyone is wealthy, access to education, healthcare, and other essential services would be widespread, leading to better overall quality of life. People would have more opportunities to pursue their passions, hobbies, and interests, and they might experience greater satisfaction and fulfillment in their lives.
Moreover, a peaceful world would mean that people could live without the constant fear of wars, terrorism, or other forms of violence. This sense of safety and security would likely contribute to a higher level of contentment and happiness among the population.
Of course, achieving such a utopian world is a complex and challenging task, as it involves addressing numerous social, economic, and political issues. Additionally, the definition of happiness varies among individuals, and material wealth and external circumstances are not the sole factors contributing to a person's well-being. Factors like social connections, purpose, and personal fulfillment are also crucial components of overall happiness.
It's essential to recognize that real-world situations are rarely so ideal, and happiness is a multifaceted concept that goes beyond material wealth and external circumstances. Nevertheless, striving for a more prosperous and peaceful world remains a worthy goal for societies to pursue.
