I suppose one could take the view that in order for Augustus to implement all the changes he had in mind, at least in the functioning of the provinces, he would have to strengthen his own position at the same time: he had already made huge changes internally in Roman politics in the role of the senate. I'm starting to appreciate how masterful a politician he was: he was able to implement his own changes while at the same time strengthening the position of the princeps, thereby ensuring his work wasn't able to be undermined.
There are many suggestions that he wished to extend Rome's borders to their natural possible limits, and make use of geographical feature for frontiers, such as the river elbe... did he decide this before or after the Varrian disaster?
Isn't Rome's welfare also the welfare of the princeps himself?? If Rome isn't doing so crash hot, and the princeps is the direct representative of Rome itself, the princeps will lose all clout. For Augustus to remain in power, and ensure that the princeps remains the head of state after he is gone, doesn't he have to show the people that Rome is far better off under the direct rule of one man? By looking out for Rome's wealth and interest, he was merely making sure he remained at the top of the system, and it's two-fold, if Rome is the most powerful nation in the region, he will remain the most powerful individual in the region.
