There isn't much logic to the idea since anyone capable of making a choice would automaticaly choose the best for themselves.
Too many kids are starving , too many kids are abused, assuming it is possible to choose would be like saying all those kids chose a life of poverty and misery.
Don't make a lot of sense to me.

PS
If I had been in a position to choose I would have stuck with the ones I got as I'm very happy with the end product of thier child rearing.
