Yes, well that all sounds fine in economic theory. However, in reality Sunfish, the people who's "Qantas Jobs" are about to be pissed up against the wall probably won't thank you for it.
Do you really think that a 50 year old LAME is going to be able to obtain comparable employment after the vast majority of his industry (the only one for which he holds any qualifications for by the way) has been flushed down the globalisation toilet.
Believe it or not but the people that come up with the "Economic theory's" know about all these issues. There are ways of addressing structural unemployment. For example the 50 year old LAME could go to uni, get qualified in the field of economics and become an economist
