Well Jack having attended law school I am sure you encountered many people who said they never wanted to be lawyers. I think it is stupid to attend law school if you don't want to be a lawyer, but I am sure you encountered numerous people that said that I know at my school I did.
Furthermore, you know that many law school graduates do not pass the bar exam or even take it. That makes a substantial change in the percentage because as you know it is unauthorized practice of law to work as an attorney without a license.
I don't know what state you took the bar in, but California takes 4 months to release results and you don't get them until the week before thanksgiving when nobody is hiring. You essentially have to wait until January to start looking for work as a licensed attorney, which is 8 months after law school ends in California. The statistics require reporting 9 months after and law students really have a month to look for a job at that point.
When I was waiting for bar results I got numerous interviews and some clerk jobs, but nobody was going to hire me as an attorney until those results came in. I would be very curious to know what the numbers were 2-3 years after graduating from law school, because honestly everyone I went to school with that passed the bar has a job.
Further still money is not everything. I do not think law school is a great financial investment by any means it is far to expensive for what it is. However, being a lawyer lets you do things you cannot do otherwise. I love going to court and representing people, I get to get warrants for cops to bust crack houses, I get resolve nuisance problems through litigation and do all kinds of awesome things I could not do without a law license, but I am not making insane amounts of money either, but I love being a lawyer.
If it was all about dollars and cents I would have worked for this clinical psychologist that loved me in undergrad. He was making bank and wanted to pay for a clinical psychology degree to work for him, but I have no desire to be a psychologist it does not interest me. I am happy with my choice to attend law school.
Now with that to any OL's if you are looking to make big money law school is NOT the place to go. It is very expensive and to expensive in my opinion for what it is, but if you really want to be a lawyer when you pass the bar you have the right to represent client's and do some great things, but what you do with your law license is up to you.
