Lately, there has been something bothering me about Gensokyo's residents. (I'm new here BTW)
That something, is money.
Reimu makes a living on (rarely) receiving donations from the human village and her youkai friends, but where do THEY get the money from?
With the exception of a handfew of Touhous, it isn't stated how the girls get their funds. Sure, the wild, homeless youkai don't really have to bother since they don't have any need for money (majority of Team 9 as prime example), but the mansion owning youkai of Gensokyo would need some form of income to support their luxurious life styles. As far as I know, there is no such thing as a Gensokyo bank, so the Touhou Tops can't just live of the interest. And Gensokyo is pretty small, so I just can't see how the humans nor the youkai could possibly build an economy, when they are so cut off from the outside world.
Thus, I would want to hear your wacky theories of the Touhou girls money making schemes, or tell about existing answers provided by official work. You could also discuss who's a lady and who's a tramp, which quite surprisingly isn't always very clear (a doujin once had Ran state the Yakumo's weren't so financially well, although Yukari could easily conjure up money from thin air/rob an outside world bank through gaps).
Example:
Meiling and Sakuya probably get their wages from Remilia, but where does she get the money from? Keeping maintenance in the mansion is also pretty costly, having Flan around. Not to mention all the food and drinks Remilia needs for her party's. The amount of ink Patchouli needs for writing books would also be a fortune! And all Remi does is sit on her vampiric butt all day and eat blood cakes. If she doesn't have a reasonable source of income, her family fortune would be desimated in months!
My theory? Patchy is a walking, anemic, squishy moneyprinter.
Patchy can manipulate the elements, one of which is metal.
Gold is a metal.
You do the math.
And even if Patchy isn't an alchemist, with wood manipulation she could make perfect money bills and with metal powers sublime yen coins. That's why she gets to stay in the SDM, instead of being kicked out by Remi for doing nothing in the library. Without her Remi's wealth would vanish in weeks.
Note: We all already know about Eirin working as doctor, Keine as a teacher, Mystia owning a lamprey stand and Marisa stealing and pawning everything that isn't bolted to the ground and/or on fire. You don't need to tell about them.
