A great problem in Central Asia and India, among other places, is the selling of women into slaver. Usually sex slavery. Happens quite frequently in Iran as well from what I’ve read.
Women in this part of the world are seen as property. A daughter or a “disobedient” wife can bring a family out of debt or help a family purchase a tractor or other items which can enhance a Father or Husbands wealth or standing in the community. Daughters are not seen as contributors to a family estate. They’re more a nuisance or a drain on resources. A man who has only daughters can be taken deep into debt for dowries.
It’s not seen as fortunate on this side of the planet to have a daughter.
They’re expendable or worse.
We, in the West, find this attitude abhorrent. At the top of the world, it’s merely a fact of life.
There are several excellent books which touch on this subject. Sold, by Patricia McCormick, is an excellent fictional account of a young girl who is sold into slavery in order to bring her family out of debt and deceived into thinking that she will be a house servant in order that she go willingly.
This is a horrible fact of life for women in this part of the globe. A less mentioned facet of the sex slave trade is the number of these women who end up in the West in back alley rooms and decrepit hotels on the wrong side of town. They’re kept prisoner and when used up, murdered and tossed out like so much waste.
