Geodome, I wouldn't give advice on getting a Chem E PhD, especially since the poster said that he wasn't interested in ChemE. It seems that all you're after is money. If that is truly all you're after, then go into business. If not, then go with what you love.
Chem Es do make more money than chemists. Honestly, though, they're nothing but glorified mechanical engineers. In my experience, they do little chemistry, and a whole lotta flow rate problems and math. I'm in Chemistry because I love it. I love working in a lab.
Getting a PhD in chemistry is difficult, there is no question about that. It takes a tremendous amount of time. If you get a BS in chemistry, though, even though your job prospects may not be that great when you first get out (i.e., pretty much QC jobs and working for big chemical companies like Aldrich), you can get into a lot of different grad programs. If you're a decent (not even good or spectacular) chemist, you can get into most Materials Sceince PhD programs and be stellar because of your knowledge.
Anyway, the Chem PhD is truthfully a real b$*%(. It is a requirement for getting any faculty positions, and will help with becoming a director of a research/development team. Most of the job prospects depend on which type of chemistry that you go into. If you're in organic chem, you have a lot of prospects in the pharmaceutical industry, for example.
If you have any further or more specific questions, feel free to ask. I don't know if you're planning on pursuing a grad degree, or what your plans for your career are. What would you like to do? Where do you see yourself in 5-10 years?
