I feel like people try to make out people who have children as selfless people, but the desire to have children is more often than not selfish. People have children because THEY want children. You could make the argument that the desire is selfless because they only desire to give the child a good life, but there are plenty of children at adoption centers for those who only have this desire. To most people this idea doesn't even cross their heads because they don't just want to give a child a good life, they want to create a child to call their own. This is selfish.
