An interesting debate going on here, I follow with interest and as always an argument such as this actually teaches alternative points of view previously unconsidered.
However, I STRONGLY suggest people just drop the gender gap portion of the argument as it is taken grossly out of context, is generally misunderstood and is simply derailing an otherwise informative debate.
I have never worked for Qantas but I highly doubt their industrial motivation includes cheapening the workforce by paying women pilots less than their male counterpart.
