I've read on these threads a few times that one of the major reasons that the WRE had issues with foedarti, and fell was that the Italians were unwilling to pay taxes and fight in the army, or rather the Senators and large landowners were unwilling to pay taxes.
When could this phenomenon been prevented, and what impact would this have on the WRE as a whole?
Furthermore, based on having more revenue, could they have invested in urbanising the WRE alongside maintain a fully functional army?
