I'm not going to waste your (and my) time going into the value placed by certain people here on the CC role in general
This is being over sensitive, in my humble opinion.
The fact of the matter is that cabin crew is not a role that requires several years of training (for example, like a doctor), nor does it require professional certification (for example, like a chartered accountant.)
It does require training to meet the standards set by the regulator and a type rating.
Cabin crew not only deal with the safety of the passengers, but also perform an ambassadorial role as they are the visible face of the airline to its customers.
In short, good cabin crew are a valuable asset to an airline.
However, in the wider scheme of things, let's not over egg it?
