Wait, wait, I meant the decision to take kids as falling under family planning. What do you call that decision of taking or not taking kids? I thought that is called family planning. So, I wanted to emphasize that it is your choice if you want to take kids or not. It is not mandatory to take kids.
It is true that once I am planning to be committed into a relationship, in the name of marriage and plan on still building our world, shaping our career, it is not selfish to take that decision. It is not selfish to take the decision of not upbringing another generation. It is not selfish at all.
