Definitely agree, and this is even more of a problem in the United States than most other western nations. Work life balance should be a priority for all human beings, and Americans have much to learn to catch up in this area.
That depends on the American. There is no unified American culture anymore, which makes generalities like this almost universally false. Case in point: I've lived in America all my life and nobody I know would object to only working a day a week if they could actually live off that little money.
