I think better training would help. In a lot of ways, I think meetings are an attempt to make up for bad communication. If team size has grown to the point where team members aren't able/willing to communicate with each other outside of having a formal meeting, that's when meetings almost have to be called, to make sure everyone in the room is on the same page.

I wish the MBAs would figure out a way to minimize formal "meetings" by encouraging better informal communication. Not all situations need meetings, maybe things are better solved by a simple "walk over to Jill's desk and hash it out there". Just my opinion though, I don't have formal training in management!
