How to compose a successful critical commentary:

You should attempt to re-express your target’s position so clearly, vividly, and fairly that your target says, “Thanks, I wish I’d thought of putting it that way.
You should list any points of agreement (especially if they are not matters of general or widespread agreement).
You should mention anything you have learned from your target.
Only then are you permitted to say so much as a word of rebuttal or criticism.

Really good argument that hierarchies are needed for us to aspire and make goals--equality hurts progress because it gives us nothing (less?) to aspire for as individuals. Also, comparing yourself with others is NOT helpful. Compare only with yourself and mark progress (or loss). Focus on Incremental changes, which operate like compound interest and can turn your life around.
