If you had ever met some of the persons that run these airlines you would quickly see that the sstr trend has got nothing whatsoever to do with market forces, as is often believed, but quite a lot to do with the ability to make maximum profit possible, basically its only greed, and make no mistake about this, some of these people are animals to work for. They change the terms and conditions for new entrants becuse they can, not because they have to, they also attempt to push existing pilots to the limit, but can`t get away with quite as much, yet. Once the mindset of ` This is my dream job` , and I will do anything to get it` changes then the sstr would have to go with it.
Normally though by the time that happens, after continual early/late starts, finishes, anti social life style, broken relationships, and stress caused by anything from malfunctions to near misses { yes they do breakdown, they are only machines] and people discover that being a pilot is only just another job, better than some, worse than others, . Of course in the real world it won`t happen as we all bought into the dream { literally] and no doubt we will continue to do so.
Good Luck.
