The best thing that could happen to the US pilot workforce is foreign carriers opening more US domiciles to source what pilot labor they can
This is happening now, and I think it will only accelerate...it is only a matter of time until the ME carriers have US pilot bases. The first crack in the ME carriers' armor (of only basing their pilots in the ME) is that Etihad is now allowing come pilots to commute on a month on/month off schedule.
