??? Better tell all the people adopting Korean, Latin American and African kids that, I'm sure they'd be happy to get a few bucks back to help raise those non-white kids.
No profit in placing U.S. born non-white babies in the U.S. And no profit on placing black babies in the U.S. no matter where they were born. I don't believe for a second that anyone is turning anything even remotely resembling a profit from placing African-born black babies into adoptive homes in the U.S. The very few Asian babies that are born in the U.S. and not wanted by their biological mothers/parents are almost all placed by non-profit ethnic community groups and ethnic churches.
Are you suggesting that attitudes towards having/adopting black/white biracial or black children was the same in 1973 as it is today?
