There is a great city far far away. The people there are very happy and very prosperous. The city is filled with large beautiful structures and parks. Elegant works of art and long dancing arcs look down upon the streets below. All of the carriages float above the ground as if by magic. There are fine restaurants and magnificent plays. Performers gather around the city market places. Little children eat ice cream scream with delight and the amorous play indoors under fine silks.
But there is a price. Deep underground, far from the sunlight and the sounds of sex and laughter, there is a child who wiggles and screams all through the day and all through the night. These are no fits of delight.
It is the great machine, that fine invention which so many years ago saved an entire civilization from certain doom. It is indeed the engine of utopia. It comes at a price, this is true, but a small price to pay to allow countless lives to thrive. What is the chronic torture of a single soul when weighed against the infinite prosperity in complete health and thorough satisfaction of entire people. When any people are faced with such a choice, the great machine is the sole solution, the universal panacea.
Is it worth it, you ask? The suffering of one for the benefit of all. Is not the answer an obvious one?
