decent question. The same can be said for pretty much all areas right now though. I know med students scared that "Obama Care" will lower salaries in that field somehow, I know that I saw on the news awhile back that even Ivyleague MBA's are having trouble trying to find work that a BA couldn't as easily get right now too.
Recessions come and go, but if you have a license you will find work. There is still a nationwide 11% projected growth rate for lawyers right now. That's a lot better than the projections for diesel mechanics, that much is for sure. I say that as long as people get a job that requires a license and a phd, they will be lightyears ahead of jobs that don't. Remember if you have even a DBA, your boss can replace you with his niece who only has a GED if he really wants to do so(it'll hurt his business but he wouldnt be breaking the law) but it is ILLEGAL to do the same scenario with an MD a CPA or a lawyer. That's why it's worth it to me.
