If you want to be a lawyer, law school is an excellent idea (the alternative of “reading law” is only bedievad – few people do it any more). You might end up working for a big firm and get rich, you might end up with a respectable government job, and you might end up going into private practice dealing with real people (great if you feel a bit entreprenurial, and like the idea of doing what lawyers do).
Would you want to be a lawyer if lawyers weren’t well compensated – if the answer is yes, then go to law school. If you are asking if law school is worth the time and cost in terms of getting a job which you won’t enjoy but will make you rich – the answer should be obvious. Becoming a lawyer since you think it is a meal ticket shows you are quite dumb. Pick something you enjoy and figure out how to make a profit at it.
Especially if you prefer to be a neighborhood lawyer (rather than a Wall Street “Big law” firm type), going to a fancy law school isn’t that important. Indeed, the graduates of non-elite law schools are usually better qualified to “hang out a shingle” than those in the elite schools. The non-elite law schools are often more liberal with financial aid, and of cource, in many states there are low cost public law schools (e.g. CUNY and SUNY in New York, UB and UM in Baltimore, Rutgers in New Jersey).
