The nature of the beast with this industry is that nearly everyone that works in it loves it. Sure, top level management everywhere are trying to screw every last cent out of it, but we still love the environment as a whole.
As with pilots, supply and demand with cabin crew means that wages will continue to drop whether we like it or not. I reckon QF would have no problem replacing there entire FA crews with new members on minimum wage given half the chance. There are enough people out there who would snap up the "prestigious" job as a flight attendant, regardless of the pay or conditions. The only thing stopping management is the potential losses of a mass walk out without having new crews trained to move in.
Same problem with pilots. Too many commercial pilots who will do whatever it takes to remain in the industry they love and have spent a fortune to be a part of.
ATC's no better. Crap EBA, but too sared to say "no".
