"Well," the Ambassador explained, "I've had nothing reposited that I could avoid. But since your planet has a monetary exchange, I had to pay for my office help, lodging, and so on. Synthesizing coinage would have been counterfeiting, which is against your laws, so I merely had a moderate amount of uncoined gold reposited, and I sell it on the regular Earth market as I need funds. Gold has no particular value on the Federated Planets, of course. I could get whatever you need, so long as it isn't enough to disrupt the economy any more than--well, than I have already. Let's limit ourselves to an amount that could be accounted for by an unusually good year in mining." "Sold!" Jerry said happily. "I think I can struggle along on a million a month retainer. Plus the usual fifteen per cent on advertising space and printing, of course; I'll have an estimate on that for you Tuesday. Since you can finance the whole campaign yourself, we'll leave the N.A.M. out of it. That way I can spare you the humiliation of signing an outright denial. All you have to do from now on is to keep mum. Don't even admit that you're the angel financing this campaign; that would make it look phony. I'll assign you three personal public-relations men, on twenty-four-hour shift. All your public remarks are to screen through them." "But how can I conceal my identity when I'm sponsoring the campaign?" the Ambassador objected. "That's easy. The ostensible sponsor will be a dummy organization called--um--the Consumers Fact Finding Board. Nobody but me needs to know who signs the checks." "How long will this campaign continue?" "I figure it'll take about six months to sell the public this particular bill of goods. Once we get business revived, the best thing is never to mention the words Matter Repositor again, not even to deny its existence. The ultimate goal is to make people forget they ever heard of such a gadget. The more convincing I make it, the quicker I'll work myself out of a job." "I should think you'd make it last as long as possible; that's why I asked you for a time-limit. Do you _want_ to work yourself out of a job?" "You bet I do! Then I can start selling a bigger item, launch a longer-term promotion, one that will last till Earth gets civilized, till I don't have anything more to sell. From what you say, that will take a lot longer than I'll live." "It may be none of my business, but what is this big item you propose to sell next?" the Ambassador asked, curiously. "Earth," Jerry said. The Ambassador looked confused. "I'm afraid I don't understand." "Didn't you just get through telling me, in effect, that any of your people who came to Earth could have all the money they wanted to spend? Well, I'm going to run advertising copy on the Federated Planets, and get them to come here and spend it." "But I also told you that advertising is unknown on the Federated Planets!" the Ambassador protested.
