Focusing on the relative permeability of particular class boundaries (
defined by Wright's class schema) Western's (1994) analysis does not d
raw out the most critical implications of mobility patterns for class
theory - namely, whether classes actually exist as relatively cohesive
social entities with common life experiences. Wright's ''class system
'' is not even remotely marked by intergenerational social closure, no
r are presumed class advantages commonly transmitted across generation
s. The lack of intergenerational class structuration undermines a key
tenet of class theory.
