I don't have one, as I'm more on the academic side, I've read about studies that say that for many (if not most) people, getting an MBA doesn't increase lifetime earnings.* In that sense, it may not be "profitable" to get an MBA. At the same time, I don't get the sense of an lot of people tho took it and regret it (in contrast, there seem to be many who regret going into debt to get a bachelor's degree). On the contrary, people seem happy and proud for having done it. My hunch is that this is because they are proud of the accomplishment and the satisfaction they get from being able to advance in their careers.
What is the bottom line? Basically, don't expect an MBA to necessarily "make you rich."** On the contrary, think about life satisfaction and whether your current job requires you to have a masters to progress.
* To get this result, you have to take into account the foregone earnings while you are studying rather than working.
** I don't know much about the numbers on this, but, as you may know, the statistic to look for is the average earnings for first year graduates of the programs you can realistically get into.
