why should a senior captain get mad at a new captain making close to what he makes, if they are both in the same aircraft then they are both performing the same duties
the DUTIES of a 10 year capn are the SAME as the DUTIES of a 2 year capn as long as their in the same aircraft(actually its probably less since he has a sweet schedule by now and barely flies anymore). these graduated payscales are what have lead to the bendover of ALPA across the US

heres how it should go
RJ FO 70K
RJ CAP 100K
737 FO 130K
737 CA 180K FOR LIFE
