Shrinking people was one of my Dad’s great day-dream theories. Even when I was a little kid we would talk about the benefits of shrinking people. It’s nice to see that the world is catching up with him. Slate’s Will Saletan writes:

That isn’t the way Americans have traditionally dealt with size problems. We’ve made bigger stuff to fit bigger people. The average height of American men has increased by 2.5 inches since the Civil War. The height of Chinese children has increased by nearly the same amount since 1975. Cars and houses have grown with us. A decade ago, the standard height of a ground-floor ceiling in a new American home was 8 feet. Now it’s 9. Wheelchairs have widened, as have hospital beds and doorways.
In the long run, however, economic and ecological forces are going Ashley’s way. Smaller people consume fewer resources, live longer, and are cheaper to transport. They can fit in a Hyundai. Forty-five years ago, if you were 6 feet tall, you couldn’t fly in a NASA space capsule. Now, you can barely fly coach. Blessed are the short, for they shall inherit the earth.
In fact, we’ve already shrunk people—not to fit technology, but to fit our image of what a certain kind of person should look like. That’s the second rationale offered by Ashley’s parents: A prepubescent body fits her mental age. They call her “sweet,” “pure,” and “innocent”—their “pillow angel.” The curious thing about these terms is that they’re not cognitive. They’re moral. Indeed, the parents removed Ashley’s breast buds in part because “large breasts could ‘sexualize’ Ashley towards her caregiver, especially when they are touched while she is being moved or handled, inviting the possibility of abuse.”
