Why would someone who is capable of having their own kids... want to covet these children ....from those who can't have their own? (speaking of heterosexual couples, of course)
I don't have any of my own kids, but do want to adopt some day. If those kids are going to a good family, I don't care if they have kids or not.
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.

In our Catholic parish we have a very nice couple who have two sons. They were also foster parents to children who needed homes during family crises. About 7 years ago they began to bring two children to church with them every Sunday. This happened for at least 15 months, when suddenly it became known that they had applied to adopt the children. The kids were about 3 and 5 when they were adopted. They are biological brother and sister and black children, very well behaved. The adoptive parents' 2 sons are blond boys, the oldest a year older than the black brother and the youngest a year younger than his new black sister. This family is very stable, and I do not think they originally intended to adopt any kids, but over the year that they were caring for these children, you could see the strong bonding which took place between the parents and these two children and the other two boys.
After the adoption was final, they had the two kids baptized. Both of these kids have now also received their First Communion. It was/is a wonderful story.
