There is absolutely nothing wrong with choosing to be child free. I personally feel it is selfish to have children with the way are society is racing towards self destruction.

I had and raised a daughter who is now 21 years old. I adore her and even though she was not planned it worked out ok, but I would absolutely not do it again. The pain and heartbreak associated with wrong decisions, being out of work, etc all affect the child so much more than it would have if it were just me.

My current wife and I chose not to have more children for some of the same reasons you did and we are so happy and secure in that decision. Thanks for sharing a sentiment so many are feeling and few are expressing.
