I just want to make it clear that I am talking about 1st year regional F.O. pay here.
The company invests thousands of dollars in training a new hire and now most even provide a type rating. That in itself is compensation for someone who came from bashing the pattern in a Cessna.
Its all about doing your time, paying your dues and gaining valuable experience. Thats when you can say, "I am an airline pilot and I deserve a fair wage."
Until you reach that second year I suggest that you show some grattitude for getting on the first rung of the ladder and show some respect to the guys starting over at the bottom, again, through no fault of their own.
