It is indeed an ill wind that blows nobody any good. Perhaps not the best of English grammar but what we have traditionally meant by this is that something good always comes out of something bad. For instance, the devastation wrought by a tornado brings plenty of work for the construction sector. When someone gets the sack, it is good news for the person who is employed to replace them. If you drop a half-crown in the street, then it is a fortunate occurrence for the next person who comes along, sees it and pockets it.
