I'm established now. I own a great company. I love my work and have happy customers and supportive people in my life. So I can see straight through the resentment for what it is... It's likely enough the author is observing something real in at least some cases, but it's laughable to imagine that perspective and deep insights into the minds of others (i.e., empathy) comes with success and comfort. All evidence is that the opposite is true. It's not farfetched to suppose that he sometimes reads something else (like frustration) as resentment.
