World's richest woman says 'Drink less, work more'

The world's richest woman, Australian mining tycoon Gina Rinehart, urged those "jealous" of the wealthy to "spend less time drinking" in a piece the government described as "insulting" on Thursday.

Rinehart, whose family iron ore prospecting fortune of Aus$29.2 billion (US$30.1 billion) also makes her Australia's wealthiest person, hit out at those who she said were envious of the rich.
