I've linked an interesting radio broadcast from yesterday's Marketplace. The overview: Immigrants are leaving Arizona even before the new laws go into effect that have the goal of pushing out undocumented immigrants.
At the moment, schools are losing students, houses are being abandoned, and apartments are going unrented. And guess what? The "surplus" of savings that states like Arizona "gain" by not paying out services is not enough to offset the loss of taxes and productivity that immigrants provide because they fuel the economy.
So Arizona may get its wish. But I wonder if they can afford it.
