I've spent a lot of time over the past couple of years talking people out of going to law school.
My argument against going to law school has never been about law school per se. The education I received at law school was a valuable extension of the liberal arts, even if it was not adequate training for being the kind of legal professional I became (big law firm, corporate practice).
The problem was that the cost of law school was too high. The opportunity costs are tremendous, tuition at most schools is way too high, the debt burden incurred by many law students is heartbreaking. Too many people went to law school when the Great Recession hit, resulting in a saturated market for both law school admissions and attorney jobs.
But times change. Law school applications have fallen off, largely due to a diminished job market for new lawyers. Right now may actually be the best time in years to go to law school.
David Bernstein at Volokh Conspiracy puts it in market terms. Law school applications appear to have reached the point of capitulation.
