 That doesn't exist. That would be the real test. In terms of the common sense test, it's like, well, sure, I don't want to have a lot of kids if I'm living in a 200-square-foot apartment. But what if you could live in New York City in a 5,000-square-foot apartment? What about then? How do you feel about having kids then? That's something where we could look at the super-rich right now, and they probably are actually having large families when they are able to afford that large of a place.
