You make a few assumptions in your first paragraph, who says the the training is being given by inexperienced individuals? Only you.
Knowledge and skills becoming stagnant is a culture issue with a particular set of people and that set only. Believe it or not there are ways and means to keep your knowledge about skills and techniques up-to-date and relevant. The amount of published material on paper and digitally, constant forum discussions from around the world (its bigger than UKClimbing thankfully) and training videos, that has never been easier. Also look at the support that the BMC provide to the clubs who need it most.
One thing that is lacking in the student climbing world is something like CHECC in the caving world. The BMC goes some way to mitigate this, but pure student representation and consideration would be invaluable to supporting student climbing clubs in health and safety discussion with unions and sharing skills between clubs - 'adopt a club' schemes when numbers and experience starts to dwindle.
Shifting the focus of the discussion from 'young climbers' in general to 'under represented minorities' seems a bit straw man but I'm no fallacy expert, I'll leave that to someone else unless you wish to elaborate.
Seeing as how you are so interested in my personal climbing, I often take friends and coursemates climbing who are not climbers, they may have a hill-walking background, or grew up in an area where the outdoors was never considered as a place to spend time.
So I do my bit to expose people to the hobby, some see value in it and continue, be it indoors or outdoors, some are happy to have tried it and subsequently choose not to continue. A great deal of my climbing has been shared with inexperienced people, because I love to show people my favourite thing: adventure for the sake of adventure.
People keep saying MIDAS is essential. In 3 years of university climbing and caving, I have never been on a minibus. Some clubs are lucky (or sensible) enough to have cars, local crags to get public transport to, or the bravery (sadly) to hitchhike.
Gethin: You state one of the key issues with university clubs - the high turn over rate of members. This can be knocked on the head by allowing alumni full, unfettered membership. This allows them to stay and support the club and pass on their experience, whilst still benefiting from the advantages a student club atmosphere provides. It's simple, but not many places do it.
Muppet: If you're doing ice axe arrests you're not climbing; you're winter hillwalking or mountaineering. There can be differentiation between these activities and different clubs to do them. My experience at the club level is mainly with pure rock climbing.
