republic vanishing would not result in any major jobs. all the 170/175 flying would turn into crj-700/900 flying and the 145's would turn into crj-200's. the result would be more pilots at crap regionals (not saying republic isnt a crap regional) flying for crap wages. the real way for more jobs a mainline's would be to fix the mainline cost structure, more of their managment waste/inadequette fleet scheduling than pilot pay, to allow them to be financially viable against their non-regional using/lcc compettitors.
