Of course you have a "chance", the question is, what kind of chance?
Perhaps this will put it in perspective. I've known people who completed PhD's from MIT who applied to top B-schools and didn't get in anywhere because they didn't have work experience. Academics not even elite graduate academics, does not count as work experience. Ask yourself, what's harder - getting a 750+ GMAT and a 4.0 GPA, or getting a PhD from MIT?
Look, if you have no work experience but you have top academic qualifications, then a PhD in business administration is probably more appropriate than an MBA (although many of these programs also want work experience). Otherwise, if you want an MBA, wha'ts so bad about working a few years beforehand? Is getting a job really such a terrible thing?
