I disagree, I think the bond is indicative of how unreliable and how unwilling to commit, and how much less professional pilots are becoming.
There are 2 ways (at least) of responding to that statement.
The first response is to state that, as a DEC in EK, the F/Os I have flown with so far were, almost without exception, some of the best I have flown with in over 33 years of professional aviation. Keen to learn, good stick and rudder skills, sociable on layovers and generally trying to make the best of whatever the sand pit throws at them.
The second is to say that if standards are dropping overall - well you gets what you pay for!
The reality is probably somewhere between the two.
