One would think New Orleans can survive or get by on its tourist and convention revenues to the city. Memphis a little less so but Detroit has no such horse in that race.
Sponges and leeches have only so much OPM to draw from until the well runs dry which it has but old addictions are hard to break.

[Publius]

One thing that New Orleans, Memphis and Detroit have in common is that they are ports and railheads. All three cities could continue to function in those capacities.

But to keep a port/railhead function running, you only need an employee base of 10 thousand people. That may end up being the only remnant of those three cities.

[The Antiyuppie]

New Orleans has going for it a very low cost of living, Memphis, nearly so.
