I can't judge anyone for being desperate for a child, even a second one and maybe if I were in there position I would do the same.
However IMO they do have a moral responsibility to see the surrogate as more than a vessel.
It is the inequality between them and the surrogate which puts them in a position to buy this service from her and, while taking advantage of this, they should also acknowledge the risks she is taking. They should ensure that the fee they pay includes an element of insurance to compensate the surrogate should should she suffer any sort of complications, provision for her children should she die and for the child concerned should it have any disability and they choose not to accept it themselves.
Maybe those things are in place, maybe not but to see it as a simple business transaction in which their only responsibility is to hand over the cash would be selfish and irresponsible.
I think this couple deserve credit for being willing to go public and maybe they have been misrepresented but they do confess to going for the cheapest option. Perhaps they should have gone for the most responsible option.
This needs to be regulated in India but I think perhaps also in this country. We need to acknowledge that this service exists and meets needs in both countries and it should not be pushed underground. We need to protect these women and their families as best we can with our own legislation.
I do also struggle with the idea that the agencies can refuse to pay the money to the surrogate until they approve of how she is spending it.
