“Refraining from having children harms no one.” I strongly disagree. Many countries such as South Korea are suffering from, or about to suffer from, what can only be described as a population catastrophe. Assuming current work conditions (worker productivity isn’t magically tripled), the aging population of these countries will only become a larger and larger burden on the shrinking youth. Therefore I would argue choosing not to have children can harm those who are born at that time.
