"By now, legions of tireless essayists and op-ed columnists have dressed feminists down for making such a fuss about entering the professions and earning equal pay that everyone's attention has been distracted from the important contributions of mothers working at home. This judgment presumes, of course, that prior to the resurgence of feminism in the '70s, housewives and mothers enjoyed wide recognition and honor. This was not exactly the case."
