The view that everyone should strive for marriage and children seems very centric to your identity and circumstances (male, well off, good access to resources, safe environment, economic stability). Unfortunately not everyone has these privileges. It's good to be able to think outside of your own identity and try to understand the circumstances of others, otherwise you just come off as a privileged asshole. Try telling someone with a hereditary predisposition for a very high likelihood of a deadly disease to have children... Or a woman who who has been in abusive relationships to get married. Or someone living in a constant area of conflict to raise a kid so they can be shot by a drone while praying in a tent. It's dumb. No, not everyone needs to have children. Consider your own circumstances and decide what's right for you.
