I think it is common, if one family has a servant for housekeeping in Indonesia. The fact that we have high population and it could low our GDP. So, only few people have high quality of life, and the other have low quality of life. Peoples who have low quality of life will work anything that support him to survive, one of them is become servant.
In Indonesia service for housekeeping doesn’t paid very well. Because there are many people in Indonesia, so that it will be easy to get people who want work for housekeeping.
At average for housekeeping they only get around Rp 200.000- Rp. 500.000 a month. It is equal 20-50 US$ a month.
