Prove me wrong ....

Industry vet here. As so many of us have been or are looking for jobs. Every time I see a new opening , my 1st question is why is the position open ? Cause no person leaves when their rank is good, good bonus $ etc... literally as I do my research I ask around & every time it’s true of the typical thing, no access , no coverage , territory rank is in the tank always , drug quite frankly not that good, or terrible DM etc... honestly has anyone found a decent place to join ??
