Pepperdine isn't even a top 25 law school (depending on who you ask, it's not even a top 50 school). There are six other law schools in California with better rankings. In short, Pepperdine is, at best, a small to medium sized fish in a very big pond. It's not terribly surprising that the kid's having trouble finding work within the legal field.
It's one thing to go to a lower-ranked school if there aren't any other Tier 1 law schools in the area (e.g. Montana, North Dakota, etc), but it's a risky move somewhere like CA where the market is already saturated and heavily dominated by much more prestigious law schools.
Another question is whether the JD and MBA were separate degrees or part of some form of joint program. In general, there's no compelling reason to bother with a joint JD/MBA program; the degrees have very different foci and their career paths very seldom overlap. So a person seeking a joint JD/MBA program without having a very specific reason for wanting that rather odd combination would indicate a potential habit of poor planning IMO.
