Exactly the reverse Hanoi. Ansetts demise meant that there was one less competitor, so not only did the Ansett jobs go, but more jobs would have gone when Qantas jacked up prices in response to Ansetts demise.
Free Markets and Free trade = more competiton = more efficiencies = better prices, more jobs.
My recollection is that someone got the Nobel Prize for proving this, and the Australian economy today is a shining example of what free trade does.
Of course we have at least two remaining problems - Telstra and Qantas, both of whom are warts on the bum of economic progress.
