An interesting essay: "When Equality Matters".
As an aside, I noticed the themes of this article fit the Good News. God is not an "equalizer" in how he treats people. Individuals are often treated as being very different: personality which is acknowledged, strengths which are recognized, actions which are rewarded, and gifts which are received. Yet God does desire -- and provide -- that everyone have equal opportunity to have real liberty and equal opportunity to have eternal prosperity.
