Smart people prefer to work with other smart people. Face it, it's frustrating for smart people to work with dumb people. One reason why is that dumb people tend not to be self critical and consider themselves just fine. So they are determined to remain in their comfort zone of everything from thinking to behaving.
No surprise, then, smart people flock to law school. For three years they are surrounded by smart professors. Many of their fellow students are above average in intelligence.
But the environment, like most academic institutions, is artificial. In the real world, including even some top law firms, not everyone practicing law is smart. Moreover, many of the clients are not smart.
Clearly, here we have the making of a tragedy. To be with other smart people, smart people invest three years and a six-figure wad of money to attend law school. However, after that they will be encountering too many lesser minds. Some of those lesser minds are the unemployment clerks they deal with when let go from their legal jobs and the gatekeepers for survival jobs if they are unable to secure a position practicing law.
