Having a family is awesome, but there is a reason most people have 2-3 kids and call it a day. They want to be able to provide for them, put a roof over their head, maybe send them to college, maybe pay for a wedding. There are many people who would love nothing more to have kids but cant for whatever reason, then a segment of our society who has no business having kids (Im not talking about the plumber) can get pregnant by just looking at each other.
If you don't think that having kids should be something considered from a financial responsibility, that is sad. I'm afraid too many people in the world share your thoughtlessness, and that is a big part of the problems we have in society today.
