The engineers will make good money in any field, though the managers of any high-end field are easily making more. This goes hand-in-hand with your interest in business so I'd throw in a business management minor in there if this interests you. Strong managers are extinguishing in today's world as far as I can tell, but in the way that it's extremely helpful for anyone interested. A lot of this can depend on personality though.
I'be signed a 6 year contract with the Navy for AECF(Adavanced Electronics Computer Field). Depending on how that is I might stay in, who knows. Either way I'm wanting to get a degree in electrical engineering with a management minor.
