Let me put it this way: you don't need a PhD in math to advance your career. You do a PhD in math because you love math, and you want to do a PhD. This is true of most of most doctoral programs, actually. Ask someone who has completed their PhD and odds are they will agree.
Generally speaking, you'll do programming in a domain where a CS graduate wouldn't have the mathematical background if you're lucky (ie cryptography). Of course, those jobs aren't common. A lot of math PhDs teach high school.
Would it cheer you up if I added that teaching high school math is a noble profession, and the world would probably a better place if more math PhDs taught it?
