Max Weber analyzed the relationship between religious beliefs, economic practices, and social stratification. He argued that Protestant beliefs, particularly Calvinism, influenced the development of capitalism. Puritans believed success in business signified being among the elect. This led to rational bookkeeping and pursuit of profits beyond basic needs. Over time, these habits lost religious meaning but rational profit-seeking remained. Weber observed Protestants dominated skilled trades and business leadership across countries. Religious beliefs helped determine career choices and economic involvement beyond just inherited wealth.
