iris lilies,

Have you considered the prospect for tax increases in IL? Illinois is by no means the only state with an extreme problem of underfunded pensions, but it seems to me that politicians in IL are running out of space to kick the can down the road.
Each year since 2014, IL population has decreased. In contrast the population of all the contiguous states plus MN and MI have increased.

Wealthy Illinoisians reportedly are leaving the state more rapidly than people of lesser means.

According to a report from Moody's Investor Services: "Population loss can be a cause, as well as an effect, of economic deterioration. A self-reinforcing cycle of population loss and economic stagnation could greatly complicate IL's efforts to stabilize its finances. Not only is IL caught in a political stalemate over how to address fallout from a tax cut that took effect two years ago; but its operating budget faces a long-term challenge from steadily mounting pension-funding requirements."
