I've had the opportunity to listen to a number of civil tort lawyers and they say that in the 80s it was very easy to make lots of money doing med mal and personal injury work. The money lawyers could make doing civil tort lit drew a lot of people into the profession that didn't care about the law, but were in it only for the paycheck. These people were unhappy in the profession, by and large.
Then tort reform came around and there are caps in a lot of states. Juries are "tainted" by PR, so they are reluctant to hand out awards to injured people. Suddenly, competition got harder and the "paycheck" lawyers were VERY unhappy.
There is/was a glut of baby boomer lawyers who will retire in the next 10 years, so I think the feeling that there are "too many lawyers" will be changing as they retire.
I try to keep all that background in mind when looking at figures like these.
