US: Exporting Babies

A reminder from Mirah Riben, who blogs at Family Preservation Advocate, that the U.S. is both a sending and receiving nation in international adoption, which really seems bizarre in light of the Hague Convention's insistence that domestic adoption should be preferred over international placement:
With thousands of Americans eagerly adopting and more vying to adopt, why then are American-born babies – shockingly ­– being placed out of the US by American adoption agencies?

The United States is one of a very few nations, including Great Britain, Canada and Mexico, that both imports and exports babies for adoption, or in the parlance of adoption is both a sending and receiving nation.

Why does any American child need to be taken from his or her culture to a home in a foreign land? Is it ever in a child’s best interest or are they simply commodities being transplanted because of the greed of adoption facilitators or agencies who cannot turn down any opportunity to secure a fee of tens of thousands of dollars?

While the numbers, by all counts, are relatively low, each represents the life of a child who will grow into an adult severed from his homeland: a prosperous fully functioning democracy, not a third world country or a nation in political upheaval as are many of the sending nations. How do those adopted out of the US feel when they understand their placement effectively meant that no one in their nation of birth wanted them?

How can we rationalize this practice while America is the biggest recipient of children from other parts of the world?
