I think you are asking what happens when the MLC'r reaches rock bottom. Well, I can't say for a fact, as my XH hasn't reached it yet apparently, but I would think the only place to go from rock bottom is up. And as slow as the trip is down, the climb back up may be even slower.
Will we as the LBS' see change. I suppose that depends on if they are still around and care by the time the trip is over. I believe some may never reach that point of reconnection. Some, like my XH, would be too proud to admit he had been an asshat.
