What you want is parity first, then cuts. That will require Congress exempting all medical insurance payments from taxation.
Once you get that done, then you'll know what comparable salaries are. Then you cut the teachers. Also, the state of Wisconsin needs someone on the job who can negotiate with the medical insurance operators to get them a better rate. They are paying a group rate of $23,000 per employee per year ~ even ordinary individual policies don't cost that much!
