While the famous economics prof's point makes sense, I don't believe inequality has to be inevitable. "The always will be" argument could have been applied to slavery for most of human history, and while it's true slavery remains a problem in the present day (ie human trafficking) it is not now treated as inevitable nor is it officially condoned.
