Ralph Nader, 75, has been an outsized figure in American political and civic life for more than four decades. Consumer advocate, lawyer, citizen activist and former presidential candidate -- perhaps most notably in 2000, when as a candidate for the Green party, he received nearly 3 percent of the vote -- he has also written or co-authored 34 books. Among them: the influential ``Unsafe At Any Speed,'' the 1965 best-selling indictment of the auto industry and its lax safety standards. In his latest book, ``Only the Super-Rich Can Save Us!'' (Seven Stories Press, $27.50), Nader envisions what could happen if some of the country's richest people pooled their resources and led a drive to get many changes Nader has long sought -- curbs on corporate power and big insurance companies, for instance, and third-party victories. In the novel, characters based on real people such as Warren Buffett and Ted Turner in fictional roles mobilize the people for fairness and justice.
