From day one, when we get into aviation we are taught that Safety must come first. Would you say that choosing an unexperienced, young CC over a mature, experienced one is "safe"?
Would you say a mother who gives a 2 years old all the candies he wants is a good mother?
I believe that it's immoral for an airline to trick its customers into believing that a nice, young unexperienced CC is what they want. Because if they asked the right question, "would you rather have a mature and experienced person to look after your backside, or a cute, unexperienced one" we all know what the answer would be. But of course that would cost them more, so they sell you junk food with a nice wrapper. Someone from a company with that kind of policy about CC told me recently that their policy was to keep CC an average of 2 years (2 years! You don't even know what an aircraft is after 2 years. You are beginnig to have a clue!), so as to avoid seniority (and the pay rises that go with it) and all the problems given by maternity and sick leaves, and at the same time all the fallouts of the awareness that comes with experience after a while, when you've had the time of seeing all the pros and cons, and realise that maybe the novelty of spending 20 days out of 30 in a s*itty hotel at the end of 35L very quickly wears out, and start demanding more human working conditions and treatment.
So the solution is to overlook the real value of a proper training, that takes time to build, and experience, which is given also by working side to side with more experienced collegues who pass on their knowledge, and make you see only the "funny" side of flight, forget safety!
