Darkroom - the irrefutable fact of the matter is, most of the flying public couldn't give a rats arse about who sits in the flight-deck.
The vast majority of passengers (certainly in Europe but it all started in the good old US of A) want to get there for the least possible amount of money. This is why the lo cost model is so rampant and the likes of Ryanair carry more passengers than the legacies.
Flying is routine and with the locked door policy, Jo Public almost never sees who (or how old) the 2 people up front are. The first time any consideration will be given is when it is evident that the proverbial poo is hitting the fan - and that just (almost) never ever happens.
So it's all well and good for you and others to sit in your armchair and pontificate about why YOU would never hire such people into YOUR airline - the the fact remains, YOU are not running an airline. So your opinion in fact counts for sod all. It is just that, an opinion like anyone else's. You are entitled to it and so is anyone else.
As a side note - how many serious incidents / accidents have occurred with inexperienced newbies (lets say less than 3000 hours using your yardstick - which incidentally could be 8-10 years experience in my sector of the industry) compared to the old timers at the controls? Just what percentage of Darkroom's tiny 2600 hours would have been racked up at FL350+ for over 8 hour sectors with the autopilot doing the work - gosh you really learn your trade in the cruise don't you???? Total volume of hours is not in itself the only way of measuring experience.
Without diving into the details, seems to me that the likes of American, Delta, United etc etc etc have lost more hulls than Ryanair and EasyJet (and those two companies complete a HUGE number of sectors per year combined) - clearly it hasn't been many in recent years, perhaps technology does have an impact?
