What do we have today because of Augustus?

Augustus was responsable for Patroning a vast amount of excellent Roman literature of the period, such as Virgil's Aeneid, which helped define the Roman novel and consequently our literature, he struck a balance between the concept of a monarch and a democracy, creating a strange fusion of figurehead and senator (the concept of emperor is a hard concept to understand...), which perhaps can be seen today in some countries. He was a master of political propoganda, managing to hold more power than Caesar but making it appear like his was merely "the first citizen" or "princeps"

I wouldn't go that far, but he did produce (at least as far as I know...) the first dual democratic-monarchial state in history, there's a even a dispute to whether it was monarchical, but that's another story. The sheer amount of culture that he patroned in his reign was increadibale-  he had a soft spot for the Greek philosophers that before had been considered unpopular and ridiculous, and since it was under him and his immediate successors and predessors that Northern Europe was taken over, we could say that he helped spread Greek philosophy to my country and to yours by extension. He also helped divine Rome into 14 districts or "regionaries" to help aid in it's municipal buerocracy - a masterpiece of urban administration.
