Well, planning and thorough preparation are essential for anyone who is truly ready to have children. Having children isn't just about financial responsibility, like providing for them by providing them with sufficient nutritious food and meeting all their growth needs. It's also about preparing how to raise them so they become well-rounded individuals. So, preparation isn't just about finances, but also about knowledge and insight, and how to treat them well.
However, sometimes readiness comes when they enter our lives. And sometimes the drive to work harder comes when we have children. And sometimes, even though we're financially ready, we can't have children. So, I prefer things to flow naturally. Preparation is essential. But we can't determine when we'll be ready or not. If we want children, just go for it and don't worry too much about things that are still uncertain.
It's not possible to prepare for knowledge, insight and how to grow your child if you're not financially good in the first place.
So, someone who want to have kids and they're not rich in the first place will high likely won't be a successful Dad like the criteria you mentioned above. In order to make money, people have to sacrifice time, effort and mental, they have no time to learn how to be Dad and taught their child.
I have no problem for people who set such criteria,
as long as they fulfill what they said, not just talking.
