@mars90000000,
Of the big four engineering fields (chemical, mechanical, electrical, civil), chemical engineers are the "jacks of all trades" and are often employed as "process engineers" who generally keep everything running and make the process better over time. We generally hire three chemical engineers for one mechanical and one electrical. We hire chemical engineers with decent GPA's from decent colleges for $60K/yr out of college.
Chemical engineering is also a decent pre-med and pre-law curriculum. Many grad schools look favorably on engineering degrees in general. The guy who graduated first in my class is a hot shot lawyer now.
On the "why not" scale, it's a hard degree. If you don't have a natural affinity for math and science it's not for you. Expect five semesters of calculus, five semesters of advanced chemistry and very little room for mind broadening non-engineering courses.
Don't sign up for chemical engineering because of the salary. If you don't enjoy math, science and problem solving it is not for you. If you do, the financial and professional rewards are pretty good.
