@Logicfest -- but a lot of lawyers would prefer to do most of their business in federal court. Why? That's where you get constitutional law issues and other matters that are considered more sophisticated than trying to keep people out of jail for their fourth driving while intoxicated offense.
Most lawyers make a living in a state court, but a heck of a lot of them absolutely dream of being federal attorneys. There is a lot of competition for cases in federal court, however, meaning that you've got a lot of veteran attorneys on that level.
