If you're focused purely on financial impact and jobs, then no it's probably not worth it.
But most people go back to b-school for much more than just "will I get a high paying job". Of course that's one of the reasons, but not the only important reason.
A lot of folks go back because they want and need a break from work. It's like a sabbatical. You clear your head for two years to focus on you. It's not just "get a job" but it's as much about personal/professional development as it is about anything else. Many people come out of it learning more about themselves and having a better handle on their priorities or even having a more attuned "self-knowledge" of what they are looking for in a career - what is it specifically that fulfills them. And that can be invaluable.
For example, there are plenty of engineers going back to b-school. A good number of them make good money already, and in some cases as good or even better than most post-MBA salaries. And they are well aware of that, and also well aware that they won't make much more (or sometimes even less) post-MBA. But they're going back because they want to get out of engineering. They want to move into a business career now. They don't want to be in engineering anymore. Of course a down economy makes it harder, but a lot of highly driven, highly ambitious people aren't the type to "wait around" in a holding pattern waiting for the right time. They just go after it when they personally feel they're ready, and deal with the difficult economy in stride.
Same for bankers or consultants. Many of them are highly driven and ambitious. They don't want to wait around or "time the economy" by sitting in some holding pattern of a life if they can go NOW, the economy be damned. It doesn't mean they're not scared or apprehensive about the difficulty of finding a job post-MBA, but many will still go anyway. Those jobs at the junior level burn you out, and you really have to get away from it after 2-3 years. These jobs are so all encompassing that you don't have time to really explore or discover other thing (let alone sleep if you're a banker, or sleep in your own bed as a consultant).
Same with the military officers. They get to a point in their careers (usually after 5 years) where they are faced with either positioning themselves to be "lifers" in the military, or to leave and become a civilian. It's a natural break for them - go back to school (b-school, law school, med school, etc.), get skills, become a civilian. Many aren't going to say "I'll serve another tour in Iraq and wait until the economy gets better". They will either go now, or probably stay in the military longer-term.
Are there folks who have the economy dictate their career choices? Sure. But by and large for many people their personal circumstances tend to dictate when to go to school.
Put it this way. If you live long enough, you'll see multiple economic cycles throughout your lifetime. This won't be your first (or last). Get used to it. You can't hide and wait every time something bad happens - you still have to do what you want to do, and take whatever economic realities in stride.
