Some of you guys better get off your high horse.
If you think that you are going to actually design every little detail of every project, you are greatly mistaken. You are going to have drafters, designers, and even a secretery to type your specs under you on projects that are going to be designing portions of the project. Some projects will be too large for one person to handle or your firm may get many smaller projects. Now I am not saying you blindly seel a design a contractor brings in to your office sketched up on a napkin (beleive me this has happened to me). As the PE, your responsibility to make sure everything is right. Once you go through the entire design, verify all calculations are correct, it meets codes, etc., there is nothing wrong with seeling others work. If once you go through it, there are errors or items that you don't agree with, you then can say what needs to be corrected before you take professional liability for the project.
As far as not getting paid to stamp drawings for your own employer because you don't feel he is paying you enough will be sure to either get you fired or stagnate you carreer. I have been doing this for almost 20 years at 4 different firms, and I never got a raise because my employer thought I was going to do something. If I was unhappy I moved on. You can go talk to your employer and make your case but I would wait until you did seel a few projects. What are you going to tell a future employer if he asks, "how many projects have you seeled for your current (or past) employer?". Uhh, I didn't seel any because he wouldn't pay me for it. I would tell you don't let the door hit you in the ass. Personally I would seel the projects, go talk to your employer, and if you are still unhappy, start looking.
