There definitely seems to be a lack of analysis about this. I flew back into Australia recently and we had to wait ~ 2 hrs for our luggage to come off the plane because there weren't enough baggage handlers to cope with the volume.

The representative who came around and explained this to everybody waiting at the conveyor belt seemed genuinely confused by the fact that they were unable to hire people to do this work, despite the fact that this very industry has been in the media for months/years now, with reports of poor conditions, strikes, exploitatative outsourcing, etc
