In addition to education, another thing that separates lawyers from doctors is supply and demand. Due to a massive oversupply, law graduates today have very limited employment opportunities, and, for those who are "lucky" enough to land law-related jobs, they often earn very little money. Doctors, on the other hand, remain highly employable.
But despite all of this, a brilliant television show called Community hit the nail right on the head about three years ago. The following exchange between characters Jeff and Abed, in the episode “Beginner Pottery,” brilliantly and succinctly captures the difference between doctors and lawyers:
Abed: If he wants to impress people, why join a pottery class? Why not just say “Hi, I’m a doctor”?
Jeff: Because he’s crazy. And fancy jobs don’t impress people. I mean, you weren’t impressed that I’m a lawyer.
Abed: Well, anyone can be a lawyer. You can even represent yourself. You can’t do surgery on yourself; it’s illegal. You’ll get arrested. And then you get a free lawyer.
Free lawyer. Maybe that’s why our pay is so low.
