I am actually in a VERY similar position to you. I did a UG undergrad at a top b school with 5 years experience & post-MBA title. I'm happy to see someone like me in these threads because you're right...some of these threads freak me out here, but then I step away from gradcafe world and feel content with my decision! Happy to chat more offline if you'd like!
I've gone back and forth significantly on whether to apply to mba programs//dual degrees. In most cases, this felt very redunant in light of my personal UG business background. I think because of your experience and UG business background, it will be fine. I'm sure MOST of your colleagues aren't going back to b-school, and I'm sure you know that most of them are quite successful without ever getting an MBA. My thought process is...no one can take your past 5 years career away from you. You have that on your resume and are already very marketable with or without this next degree. If you're like me, you're probably going back to this type of a program given your personal passions and interest. You're going to specialize, and I think that is a talk-track in itself. I'm not sure the 200K cost and time investment really makes sense for your background because you already have your private sector experience to rely on.
Where I think people sometimes struggle here and leave some negative feedback is because of a) not having a plan b) not having sufficient marketable experience c) accepting lower paying jobs with significant debt -- those things leave anyone with negative thoughts on any program. Don't let that happen to you. Go prepared because nothing anywhere is handed to you (no matter what degree you pursue). Coming out of Wharton, I'm sure you know that!
