Since when were obscenely rich mining companies making obscenely rich profits called 'miners'?
Miners are the people that Margaret Thatcher brought to their knees in the 1980s. Miners are the dudes with the pickaxes, the dirty faces, the high mortality rate, the not-high-enough salaries and the really really terrible lungs.
Andrew Forrest is not a 'miner', and neither is any of his sorry ilk.
(In the process of checking the date of the UK miners' strike on Wikipedia, I found this, which is too good not to share:
On 13 November 2009, rumours of Thatcher's death were erroneously circulated within the Canadian Government whilst they attended a black-tie dinner, after transport minister John Baird sent a text message announcing the death of his pet tabby called Thatcher. The news was reported to Prime Minister Stephen Harper as the death of Baroness Thatcher, and almost caused a diplomatic incident between Canada and the United Kingdom, but the Canadian Government rang Downing Street and Buckingham Palace to seek verification.)
