I didn't say YOU were saying that. It was the context for my initial post, which you jumped all over because I might have tied it too closely to Steve Jobs (and, rightly, I don't know the details for him specifically).
Yes, wealth does at least provide the *opportunity* to do a great job raising kids. However, this is only true to the extent that chasing greater wealth doesn't occupy all of one's time.
Here is an interesting study, which seems to show both of us are correct to some extent:

Basically, it's not as simple as raw quality vs quantity (which I think we both know). Just being around kids a bunch only in terms of proximity, OR only being there in too limited amount of time, no matter how quality, isn't good. And, quality doesn't mean doing something special and well-planned either. It means really being there for them, in sufficient quantity.
I'm not going to try and post them all here, but for example, Google family mealtime and any number of things from obesity, to drug use, criminal activity, and even brain and physical development. You'll find families who take time to have dinner together have better outcomes. (Columbia University has a whole series of studies called, "The Importance of Family Dinners.") This isn't exactly rocket-science. It's pretty common sense.
