Jana's actually made several million gil over her adventuring career, some from job payments but almost entirely by selling off loot (Allagan artifacts and Garlean magitek go for a lot, to the right buyer). But money is just a means to an end for her, so the money's often gone within minutes and she lives a fairly destitute lifestyle, preferring to invest in a new weapon or crafting materials instead of in businesses or anything. A lot of her unspent money also goes back to her (NPC) sister in Gridania, which is my explanation for my retainer (whom I modeled as Jana's sister) holding so much money while Jana's living on flatbread and flat ale.
