These days, such works may be evacuated if they have a humanitarian problem. But maybe you have to think about the fact that there are people like this in real life.
I thought that she and her mother were selling their bodies to survive. She is doing it for herself, her children and her family. And the money she receives is different from the money you pay her for her "kind".
The same can be said for me. When I was working as an office worker, the money (wage) I received was different from the salary I was paid.
In addition, the money you pay at the store and the money the store receives are different. I feel that this asymmetry is slightly different from what Marx called "the fetish character of money".
By the way, this is a different issue from "political change," "war," and even "poverty."
