If life it’s not fair to everyone, does that mean life is fair?

Well, no. If you look at it in a realistic viewpoint, then you’d find that no matter the fairness scale of others, there will always be injustice and unfairness in the world. If everything were fair, then there’d be no need for justice and change because fair equals just which equals perfection. So even if you were to judge it based on others perception and experiences of life’s fairness, it will always fall short even to the most successful person.
