Question

Where Does the Stereotype women are caregivers and men are bread winners Originate from?

Answer 1

It goes back to ancient cultures.  Men left the home, as farmers or hunters or traders or whatnot, while women stayed in the home with the children and cooked, cleaned, gardened, and crafted things.  It's a location issue--men leave the house to do their work, and women stay at the house to do their work (or close by).

This makes sense.  The women would need to stay home during the end of pregnancy, and for breastfeeding afterwards (they didn't have fancy breast pumps or refrigerators like we have now).  The work a women did at home was often crucial to developing goods for trade or for money, so it wasn't that she wasn't expected to be involved in the money-making process.  

As we progress into modern culture, the ways that goods are produced has changed, so even though women were still expected to stay at home, they would be removed from the money-making process.  No longer was it expected that they would craft goods for sale (often from raw materials that their husband brought it) when their husband is a banker or a lawyer.  However, the job of pregnancy and breastfeeding are still stuck with the women, and traditional jobs of raising the children were also left with them.  Aging family would often be cared for at the home, as well, and hospitals would usually expect the family (the women of the family, as they men were required to be away from the home to do their jobs and the women could complete their jobs at the home) to be involved in helping care for those in recovery.

Thus, men are breadwinners and women are caregivers.
