Iceland is a tiny nation in a big financial mess. It's still recovering from the aftermath of the 2008 global economic crisis, which caused a domestic banking collapse.

Its currency, the krona, is also in really bad shape. That's led Icelanders to pose an existential currency question: Should they abandon the krona?

One key problem is size. Iceland has about as many people as Staten Island, so there just aren't that many people on the planet who need to use the krona.

"There are more people using Disney dollars," says Arsaell Valfells, an Icelandic economist.

When Janie Guice looks at the Mississippi Delta she sees a vast, flat flood plain home to cotton fields and catfish farms. She also sees desperate rural health problems and a deep shortage of doctors to offer care. Her job: to find doctors to fill that void.

"Who is the one that is going to go back and live in a community that maybe doesn't even have a Wal-Mart? And yes, there are a lot of communities in Mississippi that don't have a Wal-Mart yet!" Guice laments.

Commentator John Ridley moved to Los Angeles 20 years ago, not long before the riots.
