That would be a lot more relevant if Mathilde wasn't the richest wizard in K8Ps by a good margin. I mean, she's got a small fief, and very profitable business (the niter factory), and then there's the EIC. The first is enough to make her quite well off (50 gold/turn, which is roughly what a dwarf grandmaster makes (and she was also getting a grandmaster wage loremaster)), the second makes her quite wealthy (I recall it was 100/turn, but I didn't find it in the info threadmarks), and the third is yet again more (175/turn), before it's even gotten into the really profitable parts of it's business.
Honestly, I expect money will get dropped before too long, because she has enough that anything below "hire army" or "build town" doesn't impact her finances.
