CMA or CPA just pigeon holes you. You can't demand more $ with a CPA license, but you can as a JD. A law degree opens more doors than an MBA. But I agree with the other comments about a joint JD/MBA, that would be ideal.

I generally tend to agree that more education is always better than less education. But, there needs to be a balance as well. I have a friend that has more degrees after his name than dollar bills in his bank account. He took the education route to the extreme and still continues to this day to go to school. At some pointe you have to make it work for you, that in my opinion is the point of education unless you are independantly weathly. I think the key is to figure out where it is you want to go, get the tools for it, and then try to get there. While preparation is always great, don't overdue it- if you get what i am trying to say.
