Gnadenburg, you are forgetting that Australian jobs will also be created if SIA was allowed in by the increase in economic activity, granted Qantas may shed jobs (or they may not), but the key to understanding free trade is that removing protection creates more jobs than are lost from the formerly protected industries and a certain mathematician (whose name escapes me) won a Nobel prize for proving it theoretically.
To put it another way, why do you think unemployment is at a record low in Australia after 15 years of prying open the Australian economy?
None of you can say free trade has failed. You are all basking in what it has delivered. Cheap cars, electronics, food, clothes and consumer goods. Have any of you any idea what it was like growing up in Australia in the 1960's and marvelling at the quality of American cars, homes, clothes and consumer goods compared to what was available in good old protected Australia? You guys have no idea what you are talking about.
Maybe Qantas should use the Koala as its logo. Protected, slow moving, sleepy and high on gum leaves.
