ever more cheaper and safer travel
Firstly you can't have more cheaper AND safer travel it's either one or the other. By cutting costs by definition you will be cutting safety. Qantas once upon a time used to have very strict MELs above and beyond what Boeing recommended. These days it's just absolute minimum, because the old MEL's were very expensive to upkeep to was considered unnecessary to maintain them. Sure it saved money but it is not safer.
Pilot wages are not going to go any lower because we are already suffering a pilot shortage and to lower the wages any more will only accelerate the pilot shortage.
Also Aircraft I am curious using your economic theories to explain how some of the worlds leading LCC (southwest, ryanair) manage to pay very high salaries yet are still running around with ridiculous airfares. Southwest have some of the highest paid pilots in the world and they have tens of thousands of people queuing up to work for them.
