Why do you think this? I never stop hearing or reading about the versatility of the JD. What are your sources? The reasoning is sound as well--the JD is really just an advanced version of the liberal arts degree in that it teaches you how to solve problems, reason, and think critically.
Why do you think the JD is so limited to law?
Advanced version of a liberal arts degree? Is that a good thing? These are the days of specialization of labor and a liberal arts degree just screams useless in the business world.
I got a liberal arts degree in undergrad, which is why ended up in law school so fast, because business people nowadays don't want twenty-something generalists that they have to mold into a specialist.
"Jack of all trades, master of none" ring a bell?
