I’m guessing Illinois downstate real estate hasn’t fallen as much, since it didn’t go up as much. But people that bought the McMansions a few years ago will pay higher taxes, utility costs, AND have trouble selling if they lose a job.
And it does seem many will want to escape out of state. Not many will want to move to a union run state to help support the government union mobs, screaming for their $100,000 year retirement money, after retiring at 54.
