In this excerpt from Utopia, Sir Thomas More claims that the best society is one in which all people work at useful occupations. This claim is based on the idea that useful occupations, or those that contribute to the "conveniences of life," are more valuable and necessary than "vain and superfluous" occupations, which only serve to support luxury and excess. More also argues that if everyone were employed in useful occupations, there would be an abundance of these goods and services, leading to lower prices and less reliance on tradesmen to maintain their livelihoods.
More's claim seems to be supported by the idea that a society that is productive and focused on meeting the needs of its members is more likely to thrive and be successful. By encouraging people to work at occupations that are useful and necessary, such a society could effectively meet the needs of its members and provide for their well-being.
However, it is also important to consider that different societies may have different definitions of what is considered a "useful" occupation and that not all work may be immediately practical or visible in its contributions to society. For example, work in the arts, education, or research may not directly contribute to the production of goods or services, but may still be valuable in terms of cultural enrichment, critical thinking, and innovation.
More's claim that the best society is one in which all people work at useful occupations is supported by the idea that a productive and needs-focused society is likely to thrive, but it is also important to consider the potential value of occupations that may not be immediately practical or visible in their contributions to society.
