Contrary to what Popa suggested, it does sometimes happen that people graduate from law school, hang out a shingle, and end up with a successful practice. I know people who have done this in the last couple years (out of town). But it is fairly rare — most people don’t have the guts to even try, because it’s not easy. It can be done, but it’s not for the faint of heart.
The law job market is just awful, awful, awful. Anyone graduating with any kind of job is extremely fortunate. Aside from (most) government jobs, lawyer jobs tend to require long hours and many have negative work environments. This is not exactly conducive to combining Torah study with work and spending time with family.
Justice Scalia has complained that too many of the brightest people go into law. He argues that society would probably be better off if many of them went into other socially useful fields in which there is not a surplus. I think he has a valid point. Think this over before going into law. Perhaps you’d be happier and make a more positive impact as a physician assistant? (Yes, they make a lot of money too.)
On the issue of lying lawyers, Popa is right! People always think of criminal law examples, but the fact is that the vast majority of lawyers never represent defendants in criminal cases.
Bottom line: don’t go to law school unless you’re really, really sure you want to be a lawyer, even if it means long spells of unemployment and feeling pressured to stay in jobs you dislike.
