One of my five children, my 26-year-old daughter, is married and her husband is 30.  They have two kids and are doing great - have great jobs - are very happy.  Her husband once told her that his own mother never really cooked a meal for them, not something he calls a meal now.  And his mother was seldom even awake for breakfast.  So, even if children grow up with a mother and father, hard as it is to believe, that doesn't mean that they ever get a meal one would call breakfast, or dinner, either.  I think for every adult who can actually prepare a nice meal there is another adult who can't, or won't.  Is a bowl of cereal a sufficient breakfast?  Not to my mind; I've had my share of them, and I would not be surprised if it was the only thing that a majority of children have before school, rich or poor.  
You know, the reason I'm happy about the 4J breakfast program is that it gives the kids a chance to talk with each other.  They need to be able to talk with each other more.
