Conversion from production line to duplicator came all over the Solar System in about ten days. Terran Electric's own staff fabricated a duplicator capable of handling an object the size of a locomotive, and plant-sized duplicators were formed, one after the other on flat cars that rolled from the maw of the huge machine. For payment, Terran Electric accepted blocks of stock in the purchasing companies, and the wealth and holdings of Terran Electric mounted high and began to look like the major company that would ultimately control all merchandising and manufacture in the System. And thirty days after the conversion came, the wheels ground to a stop. Industry was finished. Work had ceased. Plants lay idle, nothing to do--and no one to do it for them. Keg Johnson looked up as Linna entered. There was a worried look on her face that caused Keg to inquire immediately as to its cause. She tossed a diamond bracelet on the desk and snorted: "That!" Keg picked it up. "Looks all right to me," he said. "Like the real article. What's wrong with it?" "Nothing that I can tell," grumbled his wife. "Excepting that my maid has one like it. Exactly." "I'm not too surprised," laughed Keg. "I've been warning you of that." "But what's the world coming to? If my maid can afford a diamond bracelet like this, she won't be working for me very long." "At that, you're probably right. I'd treat her with the most delicate of care," said Keg. "She's my maid!" "Look, Linna. You're not up-to-date. I can predict people sleeping in gold beds and eating from solid platinum dishes before the hysteria dies out. The economic set-up has gone to pot, Linna, and we're trying to work it out." "But what's the world coming to?" "It isn't a matter of what it's coming to, it's a matter of where it has gone. My technicians tell me metals will be rated in value as per their atomic number. Uranium is more expensive than lithium because the transmutation-factor is higher. It takes a little more power and more matter from the matter bank in the instrument to make uranium than lithium, ergo uranium will cost more." "Then if this diamond bracelet is worthless, can't we get some uranium jewelry?" "Sure--if you want it. But remember it is radioactive and therefore not to be worn too close to the skin. It isn't as bad as radium, for instance, but it is bad enough. Besides, Linna, the matter of uranium's value over lithium is a matter of a few tenths of a per cent." "Um. And how much is a pound of uranium worth, these days?" "In Terran dollars about forty-seven million, six hundred fifty-two thousand, three hundred and eight." "Are you kidding?" demanded Linna. "How can Marie afford--"
