OK, one liners are not enough. It seemed simple enough to me, the point was not what one or the other is, it was an example of something that works the same way and can not be deemed "retrospective". As for your understanding of financial analysis, it would be too long to discuss here, you might wish to refresh your knowledge. Simple ROI is a very crude measure, all the companies we are talking about would certainly consider compound interest variables in their analysis.
You also miss the point on a turn down in commodity prices. If they turn down enough we may well end up subsidising the mining industry out of our hard gouged tax dollars, something that doesn't appeal to me. Don't forget the Government is porposing cash rebates for certain mining expenditure.
