Let it be this one about Australian mining billionaire Gina Rinehart.
Is she an heiress? Inarguably. And yet she has, by hard work and guile and historic luck, multiplied the value of the business she inherited several hundred times over. The “h”-word seems to be partly a gender thing. The male scions of Australian family fortunes, such as Lachlan Murdoch (the eldest son of Rupert), are not routinely described in the press as heirs. Rinehart is the only woman among the rough lot riding the mining boom at tycoon level, and none of the others probably have to read much in the papers about how they really should be able to afford a hairdresser or a personal trainer.
Oh but there is so, so much more.
