Foreign adoptions aren't cheaper. They are popular in the US because a child can be obtained a lot faster, and because there is virtually zero possibility of a biological parent resurfacing and getting a court to void the adoption and yank a terrified toddler out of the arms of the only parents s/he has ever known. If anti-abortion activists would turn their considerable energy toward fixing the barbaric adoption laws in this country, a lot more women would freely choose to carry pregnancies to term and give up the babies for adoption. An even bigger problem than the "reclaims" are the children who languish for years in the foster cares system, desperately wanting to be adopted, but can't be because courts refuse to terminate the parental rights of their chronically imprisoned and rehabbing parents.
Find me an adult that went through foster care that thinks he would be better off as an abortion victom.
