Should I get a chemical engineering degree?

I work for a group of economists and mathematicians who work together with chemical engineers within a fuels & technology group for a government contractor. I have work to keep me busy, but the largest revenue generator in my business unit are the chemical engineers. They've recently hired 4 new engineers, 2 part-timers just to handle the workload. My work occasionally overlap with that of the chemical engineers' and then they typically just take over my work. Within the business unit itself, there is also the practice, as well as the mentality that a chemical engineer can do what an economist can do. (there is some truth to that, but it's not entirely true) be been trying to study the work material on my own, but it's not easy without a chical engineering degree. Is it worthwhile start taking basic science requirements like organic chemistry at night and then eventually work my way torques a chem eng degree? This option would require me to go on part-time for some years. Or should I just pick up the textbooks, and learn the stuff my own? the people at work do notlook to me as a chem eng, but I think that it's a good field of knowledge and training to have. Thanks
