I thought I picked up on a bit of that familiar jealousy and resentment in the OP, lol. I think everyone has felt the way you do at some point. I think you deserve a shot at it before the new guy, but sometimes the boss wants to keep you where you're most profitable now without regard to your future potential. You have to be up front with them and let them know how you feel about the situation. If you're quiet, they will assume there is no problem and proceed with whatever. The squeaky wheel gets the grease, a closed mouth doesn't get fed, blah blah blah.
