Green, I believe you are implying that none of this is her choice?
Hell no, I'm saying that it's a terrible choice that rich people are forcing on her, and that is exploitation.
Trying to couch it all as if by letting these women grow and birth a child for you is doing them a favour is appalling.
The women doing this are not the ones with the power here, it's the rich people buying their bodies who are entirely at fault. If they cared about the women then they would donate to them, and not require anything in return. If they cared about the women's families they would find a way to help them.
They don't care about that, they care that they have found someone poor enough that they can buy that woman's body for 10 months, force it through pregnancy, extract the baby, and feel good about themselves because that woman's sacrifice means that her children can now benefit from the money.
You cannot persuade me that it's not exploitation of a terrible kind.
