Mr Speaker, my question is again to the Prime Minister. I refer to his previous answer where he said that his new $9 billion-a-year tax on mining would be a veritable bonanza of investment and jobs in that industry. If the supertax is really as good for the mining industry as he claims, why wouldn’t he introduce a supertax on a range of other industries—on retail, on manufacturing, on construction—as recommended by his Treasury secretary, Ken Henry?
