The social activist and former US presidential candidate Ralph Nader - whose 2.9 million votes in the 2000 election are blamed for launching Al Gore's career as an environmentalist - imagines what the world would be like if America's multibillionaires subscribed to an ideology closer to his own rather than Ayn Rand's or Grover Norquist's.

The dramatis personae include Warren Buffett, Ted Turner and George Soros, who lead a "bloodless popular revolution against the bastions of corporate power". A grateful public throws off its yoke and defeats the far right.

Although it is far too long, Only the Super-Rich . . . remains valuable as an insight into the convictions of a maverick and genuinely inspirational figure. Many will hope, however, that Nader reverts to his roots in campaigning journalism, rather than genuflecting before an unobtainable utopia.

Only the Super-Rich Can Save Us!
