With the recent cuts to the UW system, even if you are not directly affected by lack of funding, lack of funding to everyone else = more people looking for on-campus (or general) opportunities = fewer opportunities for you. However, cost of living will be waaaay cheaper in Madison than in Southern California. UW will be seeing brain drain/people fleeing the system soon, but as yours is just a Master's (not a long PhD program) you probably don't have to worry too much about that.
