The life of unfairness

This world is full of unfairness. There are people who are rich, and there are people who are really poor. There are people who live happily, and there are people who live miserably in life. There are people who life in war in their entire life because of the place that they are born in. There are people who is born to be good looking, and there are people born to be not perfect and abnormal.

If only there are fairness in this world, then I believe that this world would be in total peace. If everything is fair, there will be no rich and poor. Everybody will live happily. There will be no war and no racism, and everybody will not hate each other. Everybody will born to be perfect, and there is no imperfect.

If only this world is fair, then there will be total happiness in this world. We are living in the world without fairness, and there is no fairness that we are living in if we think really carefully.

Why does not the god grant us with fairness, and let us live in this world happily, and without any disappointment?
