In the feminine mystique, the author argued that

women feel worthless when they deny themselves freedom of expression.

Explanation:

The name "feminine mystique" was the way Friedan found to expose the idea that American society had that women's lives were fulfilled only with their roles of housewives and mothers. It was believed that in order to be feminine women were not supposed to study, work or participate in politics. Friedman argued that it was not like that and that women were unsatisfied when they did not have the freedom to express their feelings and opinions.

i think it was because of how protected egyptian civilization was was which allowed them to evolve without much outside influence.
