Ah - from reading your comments on the other answers I think I understand what you mean here. The fact that the situation is so bad that it can hardly get any worse, could be seen as a positive thing - its so bad, it can't get any worse, so that's good isn't it - this is as bad as it is going to get? Well yes, I guess that is one way of looking at it, but it would sound very odd, even perverse to most English speakers to say that it is a fortunate thing that things are so bad they can't get any worse.
