Equal Is Unfair: America's Misguided Fight Against Income Inequality
The book I linked to is a couple hundred pages long, explores moral and practical issues, and has almost 20 pages of notes and citations. Far from attempting to "kill the discussion", which is in fact what your blithe comment is attempting, it explores the topic of inequality in a uniquely deep way.
It is a worthwhile book and, even if you disagree with it, I think you'll find it intellectually stimulating. If you think you'll read it, I'll happily buy you a copy, just PM me.
