I think where you miss the point is that pay generally reflects a level of education/training. Also ability/experience plays a role.
And you can never compare 8 weeks worth of cabin crew training to the amount of education most of us in the pointy end have.
I would love to see the newest recruit in the back who can hardly make coffee earn $50 000 a month - just like me. With the proviso that the CEO / MD and all management then also earn that. OK?
