Class structures have undergone important changes in recent decades wi
th the rise of post-industrial societies. Clark and Lipset have recent
ly interpreted these changes as evidence that class is fragmenting and
losing its importance. We reject their analysis. The birth of new sou
rces of inequality does not imply the death of the old ones. We review
empirical evidence that shows how class-based stratification continue
s to be a central factor in social stratification. Clark and Lipset al
so argue that class affects politics, the economy and the family less
than it used to. Their conclusion is based on a selective reading of t
he empirical literature. We discuss the countervailing evidence and co
nclude that class effects persist.
