How did expansion affect Roman society and culture?

Sallust was not alone in his feelings. By the second century B.C.E. the Romans ruled much of the Mediterranean world, and tremendous wealth poured into Rome. Roman institutions, social patterns, and ways of thinking changed to meet the new era. Some looked nostalgically back at what they fondly considered the good old days and idealized the traditional agrarian and family-centered way of life. Others embraced the new urban life and eagerly accepted Greek culture.
