Brokencode, use the numbers as a guide but don't let them dictate what you decide to do. If you want an M.B.A., go for it. If you decide you want a J.D., go for that. Keep in mind that you can make a living as a lawyer from a strong regional school as well. However, if pecuniary interests are your primary motivation for attending law school, I'd recommend reading through some of the threads on this site and talking to students about the experience. Although manageable, it's difficult, and if you're not 100% committed going in, you will not enjoy it. What's important is your motivation, not your age.
