I would say very few people make WP without spending (either personal or corporate) at least $10k a year on Qantas, majority probably much much more.
(yes I know it is possible to construct an overseas purchased DONE/ YUP runs for less than that - but that is a small percentage)

Any half decent profit margin puts the contribution well ahead of QP members.

Now if you paid a few grand for lounge access...
