If there's a "beggar king" like there is in every Asian country/city that controls these women, it just means that these women have to give-up 1/2 of the money they make.
Whether there is or isn't, they still live terrible lives. These women and their children are at the absolute bottom rung of society.
I don't have a solution as I do feel bad about them, but if people throw money at them, more will show up every week.
