Where will a "proper wage" (whatever it may be) come from?
In a nutshell changing the flying school/club business model. Diversify to offer more associated aviation related products and services to the wider market.
There's a lot of people out there interested in flying/aviation but will never have the resources or opportunity to realise an ambition to fly.
There's so much more to "flying" than an hour or two every now and then - it's an interest for life.
