In 1930s', Rare Earth Metal Shone, as to make telephone, took every connection available, in political sense. Now Telephone needn't waste such presious metal, yet often does.
Same With ALL electrical Goods. Cord for instance should be made of steel, Not Copper. Although Iron is Ferrous, In Right mix, Precious metal could be vastly reduced in quantity used up.
Instead, mines process copper ore to make building siding or Planters. Yuk.
Waste Is Waste & that means greater cost & short useage. Maybe Graphene electrical cords.
