There's a more transparent and straightforward pathway to a lifetime appointment as a federal judge (which actually pays OK and has many social perks) than there is to a tenured professorship in most fields. Judges have Solomon-like-life-and-death power, and the lawyers who argue before them (often successful, high-status people in their own right) are professionally obligated to suck up.
By comparison almost all professorships are like becoming the most important hobo on a given street corner.
Yeah, it's mostly either students or academia who admire their hobo kings.
It's kind of like a sport like tennis. If you're in the system, you think that the world number 150 tennis player is amazing, but they barely make enough to afford travel to the matches.
In all fairness though, it's very difficult to become a judge. At least in my country, you have to have been both a defense lawyer and a prosecutor in order to become a judge. It takes many years of experience that is not easily gained.
