that's an interesting take. and although i can see the fit, i prefer to look at it from a wider lens of children taking the torch from parents, debts and all. the first step of the harrowed journey to adulthood, in this case.

you can take prostitution specifically out of it, and still see lots of instances of children being burdened with the idiosyncracies of ancestors and environment. a child overcoming an unspecified gluttony of parents and society, if you will.

IMO one of the reasons that make that movie such a masterpiece is that it can totally 'change' depending on the viewer's perspective.
