theDudeAbides is spot-on correct.Quote from theDudeAbides:
Late to the party, I'm afraid. Recruiters will not roll the dice on you as they have a thousand folks with the experience they value more (and no slots to fill them in).
Despite your VP title, an MBA would set you up for an associate level position at a bank...and you would likely be the oldest one by quite a bit.
Update this thread with what specific "front office" job you are looking for and maybe you will get a bite. It's brutal out there, but things will be different by the time you finish school.
The question you really need to ask yourself is why you essentially want to "start-over" again, if it is feasible, and if it will be worth it to you (you can also expect a substantative paycut ... you have after all, reached VP level).
If so, go ahead and get the degree, but expect to struggle to get a position (anything is possible, and things won't be bad forever), and work with people who will be 10 years younger than you, have more energy, no life, and be willing to work the 18 hours a day required for success in this field.
P.S. And don't foreget about out-sourcing ... those guys ain't no joke either.
