I am a chemist and I think I would be unhappy as an chem engineer even making 185K. Money can motivate your choice however, if you are doing a job you don't enjoy, life is miserable.
However, if you are not sure of what you are suited for, taking the engineering path is a good first choice because as a engineer you would have the theoretical and practical/industrial opportunities that the programs give you. In industry a B.Chem Eng has a much higher ceiling (if any) when it comes to advancement (well, an MBA along the way does help). It would not be too difficult I think to just switch to a pure chemistry/academic career either if you find that suits you better - you could apply to grad school from that point. However to go from a B.Sc. chemist to an engineering career would require more undergrad courses in the engineering program to get your second degree.
