Is a PhD valuable\marketable?

I do think it’s important to look at it from a future perspective since this degree will be obtained in 4+ years from now. The professor that i really admire at my school is one of the few in CJ that have done a lot of work in biosocial factors relating to crime. I’m more interested in researching the newer theories that integrate biology and psych rather than only focusing on the old school approach of just sociology. I guess you could say that i like being able to integrate “hard sciences” into CJ because i’m also interested in the epidemiological aspects of violence. I’ve even contemplated getting an MPH for that.

I also understand, however, that at the end of the day, i need a job! I recognize that my interests are rather narrow, so at this point it’s just a matter of A) what is going to allow me to do the most research in my line of interests and B) what is going to most likely land me a job. I have to find the middle ground. This is a very important decision, so i don’t want to waste my time on a PhD that isn’t going to help me.
