If you want to help X, help them because of the value of X, not because there exists some Y who is >>> X.
I agree with that.
However inequality in practice has been called the most important problem.
Here is a quote from wikipedia:
2013 Economics Nobel prize winner Robert J. Shiller said that rising inequality in the United States and elsewhere is the most important problem. Increasing inequality harms economic growth. High and persistent unemployment, in which inequality increases, has a negative effect on subsequent long-run economic growth. Unemployment can harm growth not only because it is a waste of resources, but also because it generates redistributive pressures and subsequent distortions, drives people to poverty, constrains liquidity limiting labor mobility, and erodes self-esteem promoting social dislocation, unrest and conflict. Policies aiming at controlling unemployment and in particular at reducing its inequality-associated effects support economic growth.
The effects of inequality are massive and effect almost every facet of life. It would be hard to find a bigger problem than inequality.
The other part of my post was due to comments I have seen regularly that state that 'If someone doesn't have a job then I shouldn't have to give a penny to them. They can die because of evolution, they are unfit to live' type posts. Your post seemed like one of those because saying inequality is good is a prerequisite for such views and it may be a veiled attempt at excusing terrible conditions for the poor. Those comments may well not be aimed at your previous post, unless you are actually espousing those views. Not saying you are.
If anyone has any problems with a Wikipedia link, then I would like to remind them that the article has plenty of references which are a click away.
