I also have wants, I want to own a BMW X5 3.0D SE - but i can't afford it (mortgages, kids etc take higher priority). That particular model has also gone up in price lately. Do i complain about it? No! - i drive a cheaper vehicle.
I see travel as a want for most of the population ie it's not going to kill you if you don't travel or can't afford to travel on Qantas. I can't understand why there are complaints about a want. It's like a two year old having a tantrum about wanting a lolly.
That's the point. You can't afford an X5 so you drive a cheaper model. There are probably about 20 different cars of the same ilk (if you go right down to the "soft-roaders") that you can buy. There is healthy competition in the car industry and choices abound.
Unfortunately the same can't be said of Airline travel. There are 2 serious options locally, and by cunning use of rewards schemes and other privileges they both encourage loyalty to their particular brand. This then often steers you down the same path internationally, so even where there is theoretically more flexibility, the reality is that slavish adherence to the chosen one is the norm. This is why tobacco companies spend zillions on packaging.
Is this our own fault? Partly -yes. Will abuse of their market share have a detrimental outcome for Qantas? Possibly. Will I ditch them (and my Gold status) to make a point. Unlikely. But I am shat off with the new price of my lolly so I needed to vent.
