I don't see much of the wealth from the mining boom helping all Australians. It is depletion of a finite resource and the voracious appetite of the miners for skilled workers and the voracious appetite of China for metals (pushing up our dollar to record highs) hurts many other sectors within our country.

A mining tax that taxed true excess profits (say > 15% return rather than anything above the bond rate) would have been fair and reasonable.

Selling dirt is not the way to a prosperous future in the long term. Look at Nauru.
