Final answer:
The statement that Americans work chiefly for job satisfaction rather than money is false; financial needs are a significant motivating factor. The market revolution did bring substantial changes to the U.S., and the notion of separate spheres did help the middle class distinguish themselves from the working class.
Step-by-step explanation:
The statement 'Today, the majority of Americans work principally for job satisfaction, not for money' is false. While job satisfaction is important to many workers, most people work primarily to earn a living and support themselves and their families. Various economic studies and surveys highlight that compensation, job security, and the cost of living are significant factors in why people work. However, this does not negate the fact that job satisfaction plays a crucial role in an individual's overall wellbeing and productivity at work.
Regarding the historical context provided by Exercise 11.3.1, it is true that the market revolution brought many social and economic changes to the United States. This period in American history saw a shift from manual labor and home-based workshops to a more organized system of mass production, which influenced the social fabric and economic structures of the time.
In terms of the notion of separate spheres and the Cult of Domesticity (mentioned in point 3), which suggested a societal division between a domestic private sphere for women and a public one for men, it is true that this concept allowed the American middle class to distinguish themselves as separate from and perceived as superior to the working class.
