If your third year of tuition at Harvard Law School could be forgiven, would you agree to practice public service law for the five years immediately following graduation? Elena Kagan, dean of that law school, announced such a program today. If you intended to go that route all along, then lucky you! Will this cause others not so inclined to sign up anyway? Currently, that year of tuition costs about $40,000. How much will a new associate earn in private practice at a respected firm? It would be interesting to see how many graduates take the offer.
