David Murray has made a fool of himself.
Throughout the last decade, Qantas has consistently said that it has failed to make an "Adequate return" on its capital without specifying what an "Adequate return" would be.
Similarly, Qantas has consistently refused to state what the "Structural Issues" are with respect to its employees that are affecting productivity.
One must therefore conclude that the only "structural" issue is that the employees are paid too much and must therefore be replaced with something cheaper and of lower quality.
This conclusion has been bolstered by the fact that Unions have consistently offered to revamp work practices in the interests of increased productivity, only to be rebuffed and stonewalled by management.
