Gary,  Nationally, nothing; internationally, everything within the law or how it is interpreted at the time. The out of state immigration is going to become an even more contentious issue for Oregon now and in the future. From a purely economic standpoint it makes sense for a public employee to stick out employment there and then move to OR after retirement where the cost of living is lower. Unfortunately, markets quickly adjust, hence the rising price of homes and rent folks are seeing in the Valley. Current homeowners in the Valley can make a bundle by selling their homes and moving to a better location and visit OR for all the good free stuff until overpopulation ends all the free good stuff.  Additionally, OR is attracting the lower classes because of the generous public assistance programs. Oregon could very well be caught in a negative economic perfect storm.  Add in the eventual "big one" earthquake/tsunami and I wonder just how attractive Oregon is?
