How does Cynthia Ozick use imagery in Rosa?

Ozick's imagery of Miami Beach is reminiscent of the comcentration camps. Where the Warsaw ghetto segregated and confined Jews, Miami Beach confines the elderly. Younger people are segregated from the elderly by fences: the gay men at the beach, the receptionist in her "cage." Ozick even described the elderly as "scarecrows, blown about under the murdering sunball with empty rib cages" bringing to mind images of emaciated concentration camp prisoners.
