I also agree with Bob Forer 100%. You have a very interesting job both in terms of the problems studied and of the politics you have to deal with. Maybe not always fun, but interesting none the less. And you get to ride in garbage trucks and police cars!
Perhaps you would accept a pay cut. If you made less than $460K per year, they'd be making money off you.
