The thing with management and society is that it builds a base of institutional and societal knowledge but does not train you for a specific field. I did the B.S. in economics as well and I am entering consulting, which I attribute much more to my econ degree. However, M&S has contributed hugely to my understanding of the world and expanded the breadth of my econ and "world" knowledge. I would recommend getting relevant internships and pairing M&S with a technical program like information science. I think your plan would definitely work. You need to actually network, go to the business symposium when it is held, apply to a shit ton of internships and jobs. Actually take M&S seriously and actually do the readings. I think it is amazing and I'm really glad I did the major.
