This reminds me of a former boss. He was complaining about the clogged up freeways at 3 pm on Friday. "There's a lot of people not working very hard," he lamented contemptibly. As if he knew what every person in every one of those cars does the rest of the time.
There is a real problem for so many of us (and I'm certainly guilt of this at times) not being able to say, "Hey, maybe I have enough," and instead trying to get a bit more. As if more money would solve the other issues we're trying to paper over.
