Not quite.... It IS about the pay, the problem at the "commuter" I.E. regionals is, the only ones who can pay their bills are the captains (or some topped out FO's with well to do spouses) So in that case, it becomes all about the upward movement to a captain seat..... Look at the majors and how many more senior FO's that COULD hold captain that don't because of the schedule. They CAN AFFORD to support a family on FO pay and don't have a complex requiring the 4th stripe. So they take the schedule over a little more money and a title.
