@Pigeotto oh my goodness you need to do a lot of reading around this and just THINK. You seem to regard employing a surrogate to carry a baby as similar to hiring a nanny, it is completely different. The 'surrogate' (birth mother) literally builds the child within her body (yes, even if it's not her egg). The baby's whole world is her, the sound of her voice etc. Then they are ripped apart, often immediately after birth. We don't even do that to puppies and kittens.
'If everyone was consenting', um aren't you forgetting someone? The baby cannot consent to this (and would not if they could speak). Who is looking out for them?? The situation is ripe for exploitation of poor and or vulnerable and naive women. Babies should not be ordered up like choosing a pizza, it's wrong.
