In our time...

"In our time, all Greece was visited b a dearth of children and general decay of population...This evil grew upon us rapidly, and without attracting attention, by our men becoming perverted to a passion for show and money and the pleasures of an idle life."

Polybius

"We liberate slaves chiefly for the purpose of making out of them as many citizens as possible: we give our allies a share in the government that our numbers may increase; yet you, Romans of the original stock, including Quintii, Valerii, Iulli, are eager that your families and names at once shall perish with you."

Augustus
