I think you are wrong, on many points.
I don't think kids should set a goal of wealth, prior to having kids - one could always argue, "not now, I need more wealth."
Just have kids - certainly, you should be able to feed them - but that ain't real hard, you know.
I didn't say wealth, I said success. That means different things for different people, right? I think that people should at least get themselves established before taking on a lot of debt and responsibilities before they have had a chance to live a little. What's wrong with that?
