Matching Quote

"A new kind of woman with deep-rooted values is changing the way we live. Market researchers call it "neo-traditionalism." To us it's a woman who has found her identity in herself, her home, her family.... She is part of an extraordinary social movement that is profoundly changing the way Americans look at living—and the way products are marketed. The home is again the center of American life, oatmeal is back on the breakfast table, families are vacationing together, watching movies at home, playing Monopoly again. Even the perfume ads are suddenly glorifying commitment."
