This is bad news.
It's not just because mining is Australia's most important economic sector: Australia is also an enormously important supplier of resources to the fast-growing economies of East Asia, where so many of the world's products are now manufactured. The mining super tax will cause prices to rise on the raw materials that are the key ingredients in so many of those products. And that means the levy from "down under" truly is bad news for the overall global economy.
With the newly announced mining super tax, Australia has shot itself in the foot. In doing so, unfortunately, it may also have peppered the rest of us with buckshot.
