According to Max Weber, the Protestant ethic was a central factor in the birth of capitalism. He argued that the values associated with Protestantism, particularly Calvinism, promoted hard work, frugality, and a sense of individual responsibility, which contributed to the development of a capitalist economy. This ethic helped to create a culture that valued economic success as a sign of personal virtue and divine favor.
