You mean, Apart from better sanitation and medicine and education and irrigation and public health and roads and a freshwater system and baths and public order... what have the Romans done for us?
For the Celts they succeeded in conquering (not the Irish/Scots or the Picts) with hundreds of thousands slaughtered and literally millions enslaved, the price of that progress was very high. Were they alive today one could ask Vercingetorix and Boudica what they thought of Roman civilization.
All right, but apart from the sanitation, medicine, education, wine, public order, irrigation, roads, the fresh water system and public health, what have the Romans ever done for us?
Concrete. Capece?
