Yes, the first issue is that our legislature, like most, is infested with lawyers, meaning UI grads. Everybody understands that the funding model is completely jacked. In fact ISUs state lobbyists (for lack of a better term) and Leath thought a reworked budget model was a done deal because the BOR and Branstad were fully on board. There's plenty of fat at ISU, but relative to its peers it is highly efficient.
On one hand, though, ISU really has two choices, either stop taking all qualified students or raise tuition and let some market forces go to work. I do think with the ultra low unemployment, and rising costs we will see a major correction in enrollment in the state. We are already seeing it in the community colleges, which are typically more directly impacted by unemployment rates.
1) Last time a saw a breakdown of professions in the legislature I think there were less then 10 attorneys. And in general, it is also not true that most legislatures have a huge number of attorneys.
2) I would bet that not all got a law degree from Iowa...See Jack Whitver. Because there is another law school in this state and some might have went out of state for their law degree.
