What some are not informed about, at many of the majors there are numerous contractual means to earn a few bucks more. Those rates are basic rates. Add in per diem, add in international override pay, leave payback (easily done for flying international, not so for domestic), open time pickup, flying on day off override (when working only 12 days a month, easily done). These are all available, IF you want a money lifestyle. If you want an easier lifestyle, then do the minimum.
The big difference is, ready?, choices. What choices are available here? The only one I can think of is the, if you don't like it, blah blah. But many don't have that choice to continue elsewhere. Age issues (oldies) that need some retirement cash, nothing available in the home country or not the best to raise a family, etc, etc. and this is where they have many by the short hairs. There will always be a solid cadre of pilots here that have little choice and "have" to stay. And that's one reason they can keep our conditions so miserable.
It's not about leave here as a captain, join a legacy and instantly make $350k a year. It's about job and pay comparison for doing a third more work and close to half the pay. This place is not marketed as a Allgient, Ryan Air, Spirit, whatever low cost comes to mind. It is branded as a luxury airline with impeccable service. And who delivers that? The employees.
