Not just that, but if we rank everyone, some people will inevitably be worse than others. Should those at the bottom be condemned to poverty?
The lesson of the GINI coefficient and the psychology of relative wealth, is that absolute, material well being isn't the issue. The issue is whether people think the cards are so stacked against them, that they will never win.
So the answer is no. We know that condemning those at the bottom will result in civil unrest. Everyone needs to live in dignity, or there will be violence. Psychology has pretty much determined this to be a fact of human nature.
However, this doesn't mean we should have equity. People should be rewarded, and people should also have something to strive for. It's the dignity of the common person which has been eroded over time.
The actual discussion is about the degree of which government should handle re-distributing wealth to the lower class and to what degree the middle and upper class is responsible.
The “divide” is that politicians on both sides who’s actions don’t always match their stated positions.
