Is life fair?

Although seemingly unfair events may occur to certain people, is the likelihood of that any more or less fair for one person over another?

Take the lottery for example. A rich person plays one time and wins big. Yet another impoverished person invests thousands of dollars over decades, and never wins anything. Is that unfair?

Wouldn’t the lottery be a good example of life in general? We all have the opportunity to live. But we also have the opportunity to rise by hard work, or fall by unforeseen circumstance.

As well, why are claims of “unfairness” typically attributed to bad events? Shouldn’t a person also validly claim “unfairness” upon receiving a large inheritance?

Is life fair? Someone’s child is killed, or abused. Mine is not. Shall I proclaim fairness in the name of my child? Why shouldn’t I perceive my safe child as an example of unfairness, and likewise proclaim fairness upon the harmed child?
