Actually, some things never change. A reader shares an apt quote from Livy.
Ancus…raised fresh troops and marched to the Latin town of Politorium, which he took by assault. The inhabitants he transferred bodily to Rome; former kings had increased the size of Rome by the absorption of conquered peoples; so the policy was not without precedent. The Palatine hill was where the Romans first settled; on one side of it were the Capitol and Citadel, subsequently occupied by the Sabines; and on the other lay the Caelian hill, occupied by the Albans; the Aventine was assigned to the new comers, and they were joined soon after by others from the captured towns of Tellenae and Ficana….
One result of these enormous additions to the population was an increase in certain criminal activities, the dividing line between right and wrong becoming somewhat blurred.
– Livy, Ab Urbe Condita 1.33
Keep in mind this was more akin to the American importation of the Irish, which had similar consequences.
