"The sociologist Max Weber
classically argued that the Protestant Reformation had a peculiar effect on American work. At the dawn of the Protestant Reformation, Martin Luther preached that hard work in any occupation was a meaningful duty — a calling from God. John Calvin took this idea a step further, arguing that people should avoid socializing while working, as attention to relationships and emotions would distract them from productively fulfilling God’s will. Over the generations, these Calvinist teachings influenced Protestants, who
came to view social considerations as inappropriate and inefficient in the workplace. Protestant men were especially susceptible, as they were
expected and socialized to focus on productivity. For much of the 20th century, American workplaces were largely
designed by Protestant men."
