The National Bureau of Economic Research released a study to be published soon in the American Economic Journal that shows women’s happiness has measurably declined since 1970. It’s no surprise that this has stimulated much comment. This study covers the same time period as the rise of the so-called women’s liberation or feminist movement. The correlation demands an explanation. You can read the entire study at the Eagle Forum website. One theory advanced by the authors, University of Pennsylvania economists Betsey Stevenson and Justin Wolfers, is that the women’s liberation movement “raised women’s expectations” (sold them a bill of goods), making them feel inadequate when they fail to have it all. A second theory is that the demands on women who are both mothers and jobholders in the labor force are overwhelming.
