I don't know him or this case, but lawyers tend to often feel that way about the cases they are representing. I wouldn't think that means he's not billing.
It's ubiquitous in some regions in the US. I suspect where it's not is both very mild climates where you hardly ever use it, and severe cold where until recently heat pumps were not sufficient. Also probably old buildings.

This is a real problem, but I suspect the reason is more laziness than increasing power. That's no score card on number of classified documents one has access to.
Rather, it is time consuming and risky to determine classification level. No one is going to get in trouble for mistakenly over classifying something, but theoretically risks jail and fines for under classifying a document, not to mention the real harm that could arise from such an error.
It's important to realize the vast majority of people will not get to that certain point. Sure, you may not want to be as large as some of the famous body builders, but don't worry! That takes living your entire life organized around the central goal of getting bigger. If you are going to the gym for an hour 3 days a week you will never get to that point.
