The poor childless couple are so wrapped up in themselves, you have to feel sorry for them. They don't fight over the child's discipline, don't blame each other for the child's most obnoxious characteristics, and they miss all the fun of doing without for the child's sake. They just go along, doing whatever they want, buying what they want and liking each other. It's a pretty pathetic picture. Everyone should have children.
Children are worth it.
Every moment of anxiety, every sacrifice, every complete collapse pays off as a fine, sturdy adolescent is reached. Think back to the night of romantic adventure when your budding daughter eloped with the village idiot. The childless couple live in a vacuum. They fill their lonely days with golf, vacation trips, dinner dates, civic affairs, tranquility, leisure and entertainment. There is a terrifying emptiness without children, but the childless couple are too comfortable to know it.
