You're missing the intention of those pushing this claim: Painting Israel as running a prison intentionally bad, or vice-versa making Gaza the new Warsaw-Ghetto.
If other commentators can't note the rediculousness of putting Gaza next to Tokio, Singapur or Hong Kong, I will: A place with virtually no economy outside of NGOs, the Hamas and UN-Orgs vs. economic beacons that draw talent from all over the world.
