Im from Saudi Arabia and its common to have a maid in every household. It is seen as a sign of wealth - the more maids/helpers you have the more wealthy you are. I personally only had one as my mom didn't need help raising me and my sister but needed her for house chores like cooking, cleaning etc. We provided her with a room in our house and gave her food and clothing as well as money to send to her family that live back in India. She has been my maid for 18 years and sent her home for the holidays to see her kids. Treating her well was the main reason she kept coming back to us and staying with us instead of going back to India to settle down and live with her children. This is not the case for most households in Saudi Arabia. They mistreat their workers and in-turn leave their employers because of rough working conditions and abuse. There have been many cases where because of mistreatment of these household workers have lashed out at their employers. I am posting a link to an article of an indonesian maid who murdered her employer because of being constantly abused.
