It took a world-wide plague to turn the tide. The plague began in old China; anything could start there, with more than a billion people huddled in one area and a few madmen planning to conquer the world. It might have been a laboratory mutation, but nobody could ever prove it. It wiped out two billion people, depopulated Africa and most of Asia, and wrecked Europe, leaving only America comparatively safe to take over. An obscure scientist in one of the laboratories run by the Medical Lobby found a cure before the first waves of the epidemic hit America. Rutherford Ryan, then head of the Lobby, made sure that Medical Lobby got all the credit. By the time the world recovered, America ran it and the Medical Lobby was untouchable. Ryan made a deal with Space Lobby, and the two effectively ran the world. None of the smaller lobbies could buck them, and neither could the government. There was still a president and a congress, as there had been a Senate under the Roman Caesars. But the two Lobbies ran themselves as they chose. The real government had become a kind of oligarchy, as it always did after too much false democracy ruined the ideals of real and practical self-rule. A man belonged to his Lobby, just as a serf had belonged to his feudal landlord. It was a safe world now. Maybe progress had been halted at about the level of 1980, but so long as the citizens didn't break the rules of their lobbies, they had very little to worry about. For that, for security and the right not to think, most people were willing to leave well enough alone. Some rules seemed harsh, of course, such as the law that all operations had to be performed in Lobby hospitals. But that could be justified; it was the only safe kind of surgery and the only way to make sure there was no unsupervised experimentation, such as that which supposedly caused the plague. The rule was now an absolute ethic of medicine. It also made for better fees. Feldman's father had stuck by the rule but had questioned it. Feldman learned not to question in medical school. He scored second in Medical Ethics only to Christina Ryan. He had never figured why she singled him out for her attentions, but he gloried in both those attentions and the results. He became automatically a rising young man, the favorite of the daughter of the Lobby president. He went through internship without a sign of trouble. Chris humored him in his desire to spend three years of practice in a poor section loaded with disease, and her father approved; such selfless dedication was the perfect image projection for a future son-in-law. In return, he agreed to follow that period by becoming an administrator. A doctor's doctor, as they put it. They were married in April and his office was ready in May, complete with a staff of eighty. The publicity releases had gone out, and the Public Relations Lobby that handled news and education was paid to begin the greatest build-up any young genius ever had.
