I think it is safe to say that the airlines (regionals mostly) assume some risk by training many new hires with no prior 121 time and likely have some pilots bailing/washing out after expensive training..
Would it be more practical to advocate higher 2nd year pay as opposed to 1st to offset this risk?

Example of a current fictional pay scale:
24,33,35,40...

Example some people are advocating (double first year pay):
48,50,52,55...

Example weighted towards 2nd year and up:
30,56,59,60...

Obviously these kinds of raises might seem highly optimistic and out of reach in light of todays low regional wages. Just toying with a general direction we might take, the net gains posted above are all equal.
