Imagine for a moment that there really was injustice in the world, and that some people really cared about it. How helpful would it be to deride their sentiment as envy? Seeking something for others doesn't meet the definition of envy; even if it did, attribution of motive is still a fallacy and the side order of appeal to authority only compounds it. Sowell's tweet is a dishonest, dismissive take that could only appeal to the worst kind of culture warrior and has no place in reasoned conversation.
