The million-dollar salaries of some television journalists are a fact of life and unlikely to change, according to speakers at a New York media seminar Wednesday. Richard Salant, former president of CBS News, said there's little that the networks can do about skyrocketing salaries. "Are you going to let these people go? Ask your competition to sign some sort of antitrust agreement?" said Salant, who now is retired. He did make one concrete suggestion, however: "Abolish all agents."
