"Why are we worried about the rudd government killing the mining boom. There is always going to be demand for our iron ore isnt there?..."
You're only looking at the demand side of the equation.
You need to consider the SUPPLY side too. Are Australian companies likely to allocate their capital to projects in Australia (only to get shafted if successul) OR to overseas projects instead? This will result in job losses, decreased investment in the industry and the destruction of wealth for many many many Australians. If you think otherwise you probably work in an Australian university and trot out the same socialist arguments K Rudd and co. are now indoctrinating us with.
