This threads shows the diference between the perception of flight and cabin crew, their egos and reality.
Cabin crew don't exist for safety anymore, they exist to serve the customers. They are the waiters and waitresses at restaurants. The safety functions they provide are minimal. Even the active ones they do provide can be automated (eg door arming). Door opening and evacuation initialisation can, and has been, done by passengers. In fact there are many cabin crew around the world who almost never open doors, let alone open one in an emergency.
Indeed, the only apparent health and safety-critical tasks they do are food preparation and tending to ill passengers at the level of a Health Care Assistant. These are not skilled jobs.
As for flight crew, their role is being reduced to that of a shop manager. Certainly pilots are not equivalent to surgeons! They don't need a good degree, when they have degrees they are low-ranking three-year bachelors from low-ranking universities. There are people successfully flying large commercial aircraft in the UK with minimal training or experience. We are in a situation where crews can, and are encouraged, to sleep - without any harm resulting. Aircraft can fly themselves better, smoother, more efficiently than a human could, they can land themselves, soon they will taxi themselves and soon they will take off without crew control input. The aircraft can workaround problems, fix itself, diagnose itself, prognose itself and knows it's systems better than the crew. The majority of accidents are still caused by flight crew mistakes. The flight engineer has been successfully removed from the flight deck, the first officer will be next.
We live in modern times. Technology is making pilots redundant. A population with increasing intelligence and improved tehnology is making safety-related cabin crew redundant.
This incident was the result of egos that were too large given their relative contribution. This thread shows that many are so on awe of their own ego that they don't realise the inevitable: market forces having already started to make their jobs unnecessary and will make them totally un-needed shortly.
