I'm really sorry @JohnsShirt. Even with a fantastic childhood and upbringing as an adopted child you begin with a loss and a far from ideal situation.
I would extend that to the birth mother who would probably ideally prefer not to be pregnant in the first place as to go through pregnancy so the child is born (perhaps if termination isn't available or it's too late) and to have that child born must create untold complicated feelings and memories.
Raising an adopted child isn't easy either, the adoption board, is another source (as well as Long Lost Families) of how personal and wonderful and difficult it is.
Being a child, and then an adult, who is adopted can't be a walk in the park either, I can't begin to imagine the complex emotions and multiple times you find yourself explaining where you come from.
I maintain though that in all that surrogacy isn't the same as adoption (though I understand the natural comparison) - creating a child to be given away isn't the same as finding a family for an existing child - and as you say, surrogacy exploits women.
I saw this yesterday. I encourage those reading this short thread to read to the end of the thread. It details examples of clauses in surrogacy contracts, possibly similar to Alexandra (birth mother of Wren, Teigen's latest child) and the birth mother of Campbell's second child. They may have been asked to sign similar contracts with worse content.
