What is an example of relative deprivation?

Relative deprivation is defined as the perception of an unfair disparity between ones situation and that of others.

A simple example is a child who puts up a fuss and won't eat his dinner because he/she wanted chicken nuggets and is served tuna casserole. The child's feeling of being deprived is relative when you know that thousands of children around the world have nothing to eat at all.

Even adults have endless lists of complaints that, if you think about them, are minor inconveniences and irritations when compared to what many people have to endure.
