Kangaroo Court - You have conveniently forgotten the large number of pilots who, through no fault of their own, have been made redundant, sometimes more than once and had to start all over again at the bottom the the FOs seniority system in a new job. Picking ones airline wisely is a luxury only available to those who happen to be in the right place at the right time, lucky you.
Also don't forget what happened to Swiss Air, Sabina, BCal, Dan Air, Air Europe, Laker, Pan Am, to name but a few, you can't surely blame the pilots for these airlines collapse nor suggest the pilots didn't choose wisely when they joined?
Finally don't forget that for many of us the retirement age was sixty five when we started out, the wrong has only recently been put right but too late for some. Seventy is too much, sixty five is about right; no one had to nursemaid me but I flew with more than one co pilot who was a liability and way younger than me.
