Anyone can see, solving the crewing issue is easy.
The major airlines know this, infact many used to run inhouse ab initio crew training. Retaining crew is not rocket science either. Unfortunately, low wages and conditions (relative to a flight crew members' responsibility and skill level) have and will continue to decline.
One would expect morale to follow also, maybe not long term.
For mine, anyone choosing to become a professional pilot or continue as one needs to have either a plan B..i.e build a secondary revenue stream and/ or an early exit strategy, a passionate resolve to lobby industry groups, colleagues & employers to boost wages & conditions or be satisfied with what's on offer & live within their means.
There are choices however just like airline managers, aviation professionals such as pilots & engineers need to find ways to manage the future changes for themselves. Old fashioned values of loyalty and pride in one's company have diminshed significantly in aviation and trying to hold on to them or even resurrect them, particularly in Australian aviation, is unfortunatley not part of the programme these days. Airline Partners will tell you that.
