Yup, it's a great racket. Adopt a minority or disabled kid, get payments for the next 18 years. I've known folks who ran regular baby mills out of their homes, as their sole source of income.
What you don't know is that some of these children are virtually kidnapped from their parents. Parents who just needed a little help when the going got rough, or they dared to homeschool,etc. OTOH, I'm sure you're familiar with all the precious little babies who were in danger, and ended up dead, due to lack of diligence from these same agencies!
