I think some people who can (and have) had kids of their own want to adopt kids because they feel compelled to help. I have thought of doing foster care for that very reason, even tho my kids are grown, and theoretically I could have another one (maybe). But that may be a very small subset.

I understand "wanting to help".. but there are a ton of good families just waiting to get a child because they can't have any. Foster care is a different matter altogether.... because it generally involves an older child that needs a whole lot of intervention....emotionally, mentally and spiritually. Very good cause. :)
