Certainly the 50/50 point had not been achieved by 1960, and it is unlikely that 90 percent have achieved this Utopian Dream by 2007, (I have no document or reference to support this claim, except personal observation.)
Johnathan R. Plumber
Indoor plumbing was invented by the Romans. Its common use in the US began around the turn of the 20th century with the advent of pumps to move water. Some inventive people had used storage tanks and hand powered pumps to provide indoor plumbing as early as the 18th century but these were not in widespread use.
People had an easier way to transport waste outdoors from inside facilities.
Madam Walker, whose birth name was Sarah Breedlove, worked in cotton fields as a child and teenager. She began working as a washerwoman doing other people's laundry at a time when most Americans did not have electricity, indoor plumbing or washing machines and dryers. She continued working as a washerwoman and sometimes as a cook during her twenties and thirties until she began selling hair care products and founded her own company.

Living conditions for white Americans in the 1930s varied depending on factors such as location, occupation, and socioeconomic status. Many white Americans experienced the hardships of the Great Depression, with high unemployment rates and limited access to basic necessities. However, those who were employed often had better living conditions compared to marginalized groups, with access to electricity, indoor plumbing, and improved urban infrastructure.
