Money from land availabilities goes to the Land Office employees so don't count that. Except for your one time purchase of troops there has never been more than 400g spent in a chat period on troops. That also goes away when we discover Nationalism as the Conflict rules stop at that point. Your talking about taking in around a 1000g to pay out over 4000g. It just doesn't work.
We already know how our economy is doing. That is on the summary page of the BOV Excel file after each update.
The "cloud" is more than what we experience as players. It includes the many thousands of plebians, businesses, soldiers, towns, villages, etc of our nation.
In any case, we need to make the rules less complex and we need to make less record keeping necessary. My workload here is astronomical and there is simply no room for more and I have no confidence that anybody will step up to take ownership of additional tasks, seeing as we cannot get people to step up to take ownership of existing tasks.
