Of _course_ the child should be told about the _viciously_ racist fee structure of the adoption agency. She must be _thoroughly_ educated about entrenched racism that governs _every_ _aspect_ of American society. She should be trained to detect racist oppression _everywhere_. She must learn _never_ to trust any member of the White Power Structure, such as teachers, cops, landlords, or employers, and to understand that if any of them have a problem with her, it is because _they_ are racists. (Am I preaching to the choir here? I fear so.)
Taking tongue out of cheek: I very much doubt that your child will every inquire about this aspect of the adoption. The agency charges what the traffic will bear, more or less. In all probability, they discount the fees for adoption of black children to encourage adoption of them. To see this as a Bad Thing is looking for trouble when none exists.
