This is a complicated issue, I think, because of emotions. A surrogate mother is a woman who carries and gives birth to a baby for another woman who is unable to conceive for various reasons. There are legal complications sometimes, when the surrogate has trouble giving the baby to the couple after birth. Others claim that the surrogates only do it for the money, which is like baby selling. I don't think that I will ever be able to be a surrogate mother, but I don't find anything wrong with it.
Some women are unable to conceive and strongly desire to have children.
Adoption is a long process and does not always work out. Anyone willing to spend an enormous amount of money most likely genuinely wants a child and will be a good parent. Our class discussion raised an interesting point. Even though society and gender expectations are changing, they still retain some biases. In one of the reading assignments, the author describes how women are often related to inventions such as the use of fire and many medical remedies.
