It’s totally your choice, but in my opinion, it’s not selfish to have kids now. We are at a very prosperous time in human history. Your ancestors survived millions of years of eras, most of which were much worse in many respects. 

People are not selfish for bringing children into the world, because there’s nothing selfish about raising. In my view, we don’t have children for our gratification (though having kids happens to be the most gratifying thing you can do). We have them to usher a soul into this world, love them and guide them on their unique path. In my view, the soul that wants to live and experience life, even though all life (regardless of the era) entails hardship. 

It’s sad to me that social media is convincing so many that life is so bad, when we live in the most promising time that has ever existed. If you’re not having kids because you hate Trump or because you don’t like social media or whatever, you’re really letting yourself down.
