You have to be right. We must spend 5% of our income at Home Depot.
Childless couples who buy a home start having babies. Couples with one child generally have more.
If you don't believe babies can fuel the economy you haven't been to Babies R Us. Just look at the garbage day leavings of new parents, all the new baby stuff boxes: stroller, high chair, bed, car seat, etc., etc., etc.
Oh, and it doesn't end when they are no longer babies. My oldest is now at the 100 dollar tennis shoe stage.
