We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
I will agree with Phil, but add the following bit of information: we have more than a few students doing both. I think many CFA's see that certification necessary for clients. The MBA is a possible differentiator within the firm.
My undergrad was a double major in finance and accounting so I thought the MBA program was just a rehash of my undergrad with a pinch of "Master of the Universe" management classes added.
Today the MBA programs that I've seen seem to have more "Donald Trump Apprentice" characteristics, more feel-good classes, and less emphasis on true analytical skills.
The CFA program is much more rigorous intellectually and much harder to get through. Today the probability of passing all three CFA levels without a failure is something like 12%. I would guess that most MBA students get through their programs with a much, much higher probability of completion.
