While we can ramble about the economy, I am wondering if it is under a single Sirius wide economy, or the singular House economies that we are questioning.
In a real economy, to my limited knowledge, would lead to Bretonia and Rheinland being on a massive disadvantage and wildfire inflation compared to the other two Houses.
The reasoning is not only in the lore, but the current diplomatic climate. While Liberty is holding up best in my opinion, it is only a matter of time until trade from Bretonia and maybe Kusari begin to collapse or slowdown due to their war.
The embargo and depressed economy in Rheinland is still low since the 80 Year War back in the 7th(?) century.
Alas, this is Freelancer, and she is a fickle being.
