I don't know if there's a good way to fix the pilot pay conundrum. There are currently enough regional pilots to fill the massive vacancies that could come up at the majors...the pilots who'll leave will be the regional captains looking to move on and up. The FO's who are behind them will be happy to see them leave so they can upgrade and finally make a livable wage...the FO's will be relishing in how wealthy they've suddenly become, and at which point life will be peachy. If the major hiring continues for long enough, the FO's former FO's will have the ability to move on as well, once they have the prerequisite flight requirements...once that happens the upgrade times at the respective regional airlines become so short that it seems like a good deal for new hires to start running to their ranks again...and the crap pay seems livable...at least for the short period of time you're an FO.

The only way this really works is a mass exodus of pilots from the regionals via resignations, and that just isn't going to happen...unless upgrades at all the regionals stretches to 10 years plus...then you might see some adjustment, and people who are unwilling to suffer in the "suck".
