Life is better than death.  A person SHOULD take the time to plan and prepare for children.  As actual sentient beings, our goal should be to reduce suffering, extend life, and build better things for the present and the future.  If people who are smart and caring refuse to have children, then the only children who will get born are the ones born to irresponsible knuckleheads.  Who will teach these new children?  Who will show them an example of a better life when their natural families won’t?  The best and the brightest of our communities have the greatest responsibility to procreate, because by caring and teaching THEIR children, other children can see what is possible and be reached by another caring person who has learned how from their parents.
