Chemerinsky and Menkel-Meadow on curricular reform

From the Volokh Conspiracy:

In the New York Times, Erwin Chemerinsky and Carrie Menkel-Meadow offer a very sunny perspective on the current state of legal education. At the end, they argue that what law schools really need these days is curricular innovation:

Law school faculties, in their teaching and their scholarship, must deal with the emerging problems of the 21st century. Law schools need to develop new courses to provide students with the expertise to deal with the crucial problems of our time in fields like banking law, national security, conflict resolution, food safety, Internet law and migration policy. There should be “problem-based” seminars in fields such as public health, homelessness, environmental habitat regulation and world peace.

I don’t find these suggestions very useful. First, don’t most schools already have these “new” courses? I’m most familiar with the curriculum where I teach, but we already have one or several courses in each of those named fields.

Second, I don’t see how the listed “problem-based” seminars are supposed to help. What legal issues do students study in their Word Peace class, and how does expertise in World Peace help students get jobs? Presumably students aren’t expected to practice World Peace law. And I assume no one expects that two-credit seminars will actually create world peace.
