BS. The fact the US adoption agencies make you jump through incredible hoops and then you always stand the chance of the mother or father wanting the kid back at some point is the reason why people go overseas to adopt.
Using your logic, I guess people should just say "let them rot, they ain't American babies!" to all the discarded Asian kids.

I know of one lady who adopted four children from Haiti and she raised them same way with her biological children. Every child is wanted by someone. Everytime I turn around I'm convinced that (many/most) lawyers are the root of all evil.
However, there are many children in this contry who could easily be adopted but are not. Seems to me, though, that this varies by jurisdiction. The cases of adoption I am familiar with have all gone smoothly.
My experience: We tried adopting in 2 states. In New Mexico, we went thru all the classes and were told we would need to foster care/then adopt if we didn't want to wait 3-4 years. After getting our foster care license, my wife became pregnant. The social worker (a wonderful woman who had foster cared nearly 100 kids - mostly short term emergency stuff - and adopted 3) strongly advised we reconsider. Why? "So many kids in foster care have been sexually abused that you baby will be at significant risk - it happened to one of mine!"
Few years later, we tried in CA. Again, we were told we would have to foster care/then adopt if we didn't want to wait 3-5 years. We went to classes, then were told we would have to attend parenting classes for a couple of hours for a number of weeks - nearest location was a 400 mile round trip. And if we moved (I'm in the military) before everything was complete, we would have to start all over again in the new state. And yes, the law allows for termination of parental rights...but courts don't always follow the letter of the law. And any child we adopted without waiting for a few years would probably have been sexually abused.
In the end, we backed out. We had previously adopted 2 kids in the Philippines while stationed there, so we'll have raised 3 kids. We wish it was more but 1) overseas adoptions can also be expensive (many countries now charge a 10-20,000 adoption fee), 2) a foreign adoption would still require CA approved parenting classes (I asked if they could just interview the 3 we've got...didn't get a friendly response), 3) many countries won't allow someone with 3 kids to adopt (also mid-40s...another no-no for many countries), and 4) if we transfered, we might have to restart the whole process, with any fees paid down the drain. And yes, foreign adoptions can also take years.
My wife and I really wanted to adopt again, and we wanted to adopt a child from the US if possible - but the red tape + military life beat us. At least we successfully adopted twice in the Philippines - but don't get me started on the paperwork nightmare with the INS!
