I have always wondered why this view is so common. Nearly everyone, over the age of three, has seen that the world is not "fair" in the three year old's black and white sense. So why the disconnect?
Simple really, the entire system of human affairs relies on the majority accepting, at a fundamental level, the "Just World Hypothesis". Without it the system breaks.
If people don't accept that the rich and powerful are rich and powerful because they "deserve" it, or conversely, that the poor and unfortunates are so because they also somehow "deserve" it, the system would blow up.
Imagine what would happen if everybody realized:
1) that the World is NOT fair,
2) the World is not unfair either,
3) the World is simply what it is.
There is not enough rope or lamp posts for the resulting fall out.
