The Talmud is discussing the validity of declarations of gifts made by a dying person. In the middle of this technical discussion, the Talmud goes off on a tangent. It says if the wind is blowing north that is good for the poor people because the crops will be cheap. If it blows south it is good for the rich (or maybe the other way?) Only if blows in one direction is it good for both.
The answer is simple life is not fair. It sometimes blows good for you, sometimes blows bad and sometimes it blows good for all.
The job is a Jew is to hope and pray that his needs, desires and wishes align with the good of all so we can all enjoy.
