Tort is the best. No other field where you can ripe millions in one case. Sure you will lose most cases, but just netting one or two will make your day (AND LIFE)..
Agree with the one mentioning ambulance chasing, as hospitals will always screw up. Also, divorce is a sweet field to be in, since there usually is great resentment around and the clients can be very vindictive
I also think most law students underestimate the huge amount of money you can obtain from being a tax-lawyer working for corporates helping them to shuttle their assets out of the claws of the IRS.
I don't know much about IP, but a friend of mine is doing internship in that right now and he keeps telling me it is great as long as you can handle going in depth in particular issues, like the recent record company suits. here, in most cases, just filing a suit towards a teenage girl that downladed one track and threatening with a 100K claim is enough to make the parents settle for a few K.
Also, I see ample opportunities working for drug companies and the ones doing genetical research,but the problems with IP is that most of the patent theft happens outside US boundaries where the ability to file claims are limited. Still, I can see a promising future here as the world gets more international
I am personally strongly leaning towards tort with emphasis on personal injury or medical malpractice. I don't want to work for 20 years in order to accumulate a fruitful retirement treasury
