Lots of people in the Northeast have homes in FL, or have moved part or full-time to FL, esp. on the Atlantic side. That doesn't mean those states re "failing"; it means that A. People generally like warmer weather, especially in their later years and B. The Northeast has many successful folks who can afford multiple homes.

Similarly, it seems half of Naples, FL consists of retired suburbanites from the wealthy suburbs of the Midwest. Doesn't mean Bloomfield Hills and the like are "failing". It's the same phenomenon as with the Northeasterners but on the Gulf Coast. Talk to any wealthy white conservative Midwestern suburbanite and they go gaga for Naples.
