Are Women Unhappy?

According to this survey, despite improvements in life options, women are less happy today than 35 years ago.

They list several possible explanations and several possible alternative explanations. No one mentions, however, the possibility that more options does not always lead to more happiness.

In a game class we learned about a consumer survey that measured satisfaction in cereal choice. If a consumer only had 1 or 2 choices of cereal to choose from, they tended to be unsatisfied with their options. But on the other end of the spectrum, once the choices reached a high level (say 35 or so), the more options created a more difficult and less satisfactory consumer experience. We learned this as an element of game design, that by giving players too many choices to deal with, the game play experience went down.

Could too many choices constrict happiness?

UPDATE: The original article points to possible explanations of unhappiness: increased expectations and a wider "comparison" group (by comparing themselves not only to other women, but also men, women feel subjectively worse off while being objectively "better off.")
