As a chemist (hopefully phd within next year) I would say chemistry is the best bet as it gives you lab experience which is most important for jobs and is the most flexible if your interests change. Since its so interdisciplinary with computation bio materials chem ect. which are all important to future prospects. but as previous posters said if you do not want to be lab monkey just running mindless gcs i would say a higher degree is somewhat necessary. if you can find a phd program that includes a masters on the way like mine does you can drop out after obtaining a masters while getting paid the entire time with a stipend rather than going into debt, like some of friends in my program did.
