Caveat emptor? Absolutely.
But, don’t forget: ‘there’s one born every second.’ 
Just read the law school blogs where the masses assume they’ll be in the top decile, so they will be the lucky ones to find a job, unlike the bottom half of the class. Perfect analysis for the snowflakes. lol
But seriously, most folks do not do any more research than just reading the fancy websites of the law schools which for some reason, tend to ignore jobs, jobs, jobs.
Personally, I’m all for folks doing thier own thing on their own dime, but instead they go to LS and incur hundreds of thousands in non-dischargeable debt (federal loans) but still can’t find a legal job. It’s a moral hazard and bad public policy, IMO.
