What's the right ratio though? I try not to get angry about "the bottom 20% eats 90% of the cheeseburgers" stats until I have a reasonable benchmark, or I have a really deep understanding of the "why" and "how" of a given disparity. Two children raised in the same house with the same parents never have equal outcomes - I don't expect it anywhere else either (as a default assumption).
