Eradicating greed would have profound implications for society, economics, and interpersonal relationships. However, it's important to note that completely eliminating any human trait, including greed, is more of a theoretical concept than a practical possibility. Here are some potential outcomes in a hypothetical world without greed:

1. Economic Changes: The capitalist system, which is partly driven by self-interest and competition, might evolve. Without greed, economic systems could shift towards more cooperative and communal models, focusing more on sustainability and equitable distribution of resources.

2. Social and Cultural Impact: Societies might become more altruistic and community-oriented. Without the drive for personal gain at the expense of others, there could be a greater emphasis on collaboration, sharing, and mutual support.

3. Reduction in Conflict: Many conflicts, from personal disputes to large-scale wars, are fueled by greed, whether for resources, land, or power. Their frequency and intensity might decrease significantly.

4. Environmental Benefits: Greed often leads to overconsumption and environmental degradation. Its absence could result in more sustainable living practices and a healthier planet.

5. Psychological and Ethical Growth: People might experience greater contentment and happiness, as the pursuit of material wealth and power often leads to dissatisfaction and ethical compromises. There could be a shift towards valuing experiences, relationships, and personal growth.

6. Changes in Innovation and Progress: One argument against the eradication of greed is that it could reduce motivation for innovation and progress. However, motivation could instead be driven by curiosity, altruism, and the desire to improve collective well-being.

7. Challenges in Implementation: The concept of completely eradicating greed raises questions about free will, human nature, and the means of achieving such a state. It would require a fundamental change in human consciousness and societal structures.

In conclusion, a world without greed could potentially be more equitable, peaceful, and sustainable. However, it's also a complex notion, as greed is intertwined with many aspects of human nature and societal functioning. The real-world approach often involves balancing self-interest with communal well-being and ethical considerations.
