The "Protestant Ethic" refers to a set of values associated with the Protestant faith, particularly emphasizing hard work, discipline, and frugality. This concept suggests that these values contribute to economic success and social progress. The idea was popularized by sociologist Max Weber, who argued that the Calvinist belief in predestination encouraged individuals to demonstrate their faith through diligent work and responsible living. This ethic has influenced modern capitalism by promoting the idea that personal success is a reflection of one's moral character. As a result, many people view hard work and economic achievement as not just personal goals, but also as a way to fulfill their spiritual duties.
