The basic fact is that only half of the 45,000 or so law graduates each year will even get jobs as lawyers. I disagree with many that the ABA should clamp down on accreditation. The AMA did that in the last few decades, and while that guaranteed solid employment prospects for medical school graduates, it also led to skyrocketing salaries and medical costs. I think the medical profession has more goodwill capital to spend with the public in this regard than the legal profession, and any such move would be a very bad idea.
However, I do support measures to increase transparency and make educational loans harder to get. In-state tuition at the University of Michigan in 1990 was $6,830 per year (about $11,700 in today's dollars). It is now over $48,000/year.
Now, the teaching of law has not changed since Harvard Law School was founded in 1817. You get a bunch of students in a room. You make them read cases from a casebook. You grill them in front of the class on their comprehension of the cases. It's not a high-tech process, but it works, and can be extremely cheap. There is no reason tuitions need to be 4x higher than they were just 20 years ago. The soaring cost of legal education is really the perfect example of how incredibly dysfunctional our higher education system has become. At least with engineering or medical school tuitions you can point to the expense of lab equipment, etc. Not so with a segment of academia where students are taught the same way they have been for two centuries.
