Women still work, as they always did, but today they specialize, just as men do. Grandmother was a plumber, baker and nanny, and worked like a dog, for her family. Her granddaughter assembles microwave ovens, and gets paid in cash, by General Electric. She leaves it to Swanson's to assemble the meatloaf. She works less hard than gramma did, but she still works pretty hard.
Technology does indeed transform the nature of work, sometimes beyond recognition.
But it doesn't end it. Electricity and gas moved baking into the home. Then refrigerators and microwaves moved much of it out again. And as technology has made cookery far more efficient, we've taken up the slack by eating more varied foods, in more varied places. In a one-room schoolhouse, the teacher taught English.
