I don't think the mentality that "there are people who don't even have half of what you do!" makes a ton of sense.
Compared to the drive and desire to be the best that the mountain used to show, they seem to be showing more of a "it's good enough" attitude. To me, that isn't something to be proud of. It is lazy. Would you be happy if your heart surgeon showed little interest and decided to be "probably good enough?"
Motivation and drive is a good thing for a company and shows strength. It is certainly disappointing when someone who used to put in a lot of effort and desire to be the best, decides to quit and just settle for mediocre. Sure, they don't "have" to do anything. But a company certainly can't expect to have happy customers when they start to lose effort.
