That article is a goldmine.

But strangely, working women in areas with strong traditional values – where most people had voted against equal pay – were happier than working women in liberal cantons.

Even though their salaries were further below those of the men around them, the women in more traditional communities were less likely to report discrimination than their countrywomen in more liberal areas.

No, not strange. The traditional women don't harbor bitterness towards men and the resulting victim complex, so of course they will be happier in life.

This inside-out result probably arises from different cognitive comparisons. Women in liberal communities are less happy and notice discrimination because they automatically compare their opportunities and salary to everyone else around them, men included. Traditionally minded women perhaps base their identities more firmly on their gender roles, and think only of other women when they evaluate their privilege and opportunities.

Exactly! Traditional women feel no need to compete with men, because they know they are not men!
