The family was prosperous; Pliny the Younger's combined inherited estates made him so wealthy that he could found a school and a library, endow a fund to feed the women and children of Como, and own multiple estates around Rome and Lake Como, as well as enrich some of his friends as a personal favor.
Familien var fremgangsrig; Plinius den yngres arvede ejendomme gjorde ham så rig, at han kunne grundlægge en skole og et bibliotek, oprette et fond som sørgede for mad til kvinder og børn i Como, og hans egne talrige ejendomme rundt Roma og søen Como, foruden at han gav gaver til en del af sine venner som en personlig gunst.
