Current RJ captains will get picked up by the majors. FO's will bounce around from regional to regional with very few upgrades because the regionals won't be able to hire. They remaining regional lifers will take all the captain spots. FO's will be stuck making $37/hr until their company shuts down due to inability to staff their operation, then they'll be on the street with no TPIC time an no job prospects.

There will never be a shortage of pilots for majors, legacies and LLC airlines.
