What do you mean "socialize"? Do you have kids? Most kids can't even walk until they're about a year old.

I'm afraid I must disagree. There's no evidence to suggest that the bond between a child and its biological parents is in any way important. Further, it is unlikely that its biological parents are experts on raising children and are thus likely to raise it suboptimally, leading to a poorer quality of life in its future.

Therefore, it is more selfish to raise your child yourself than to have an expert to do it for you.

I shouldn't have to disclaim this by argument by saying that I'm not making a serious recommendation to anyone, but because parents are so defensive and irrational when it comes to how they raise their children, I feel that I must. I don't have kids and don't plan on having kids, so this is merely an intellectual exercise for me.
