What ususally blows my lid during discussions about surrogacy is when the feelings of the sperm and egg donors are is very important, while the impact of the surrogacy industry is forgotten.
Adoption is another can of worms. There has been a huge (and really mind blowingly horrible) scandal that has more or less erupted slowly here in Sweden. It has turned out that a lot of adoptions from from Chile and South Korea (and probably other countries as well) that supposedly were orphans or abandoned by their parents were not.
The supply of orphans were smaller than the demand for children to be adopted and now a lot of people in their 40’s are finding out that they were stolen.
