I don't doubt a handful of furloughed Comair pilots have displayed a sense of entitlement. A portion of those furloughed (and still on property) have never experienced tough economic conditions as adults...or even as children. Combine that with how relatively easy it was over the last couple of years for someone to get hired at Comair, and it's understandable where this sense of entitlement comes from.
I don't believe this is due solely to lack of character, but instead primarily due to lack of experience. I agree with bored that Mesaba has had their turn being beaten to death, and I suspect he/she would agree with me that Mesaba probably has a handful of pilots hired over the last year or two who share the same entitlement mentality as a few at Comair do.
