Interesting question. I'm glad you asked.
Well, it depends really on screen time, that's what we are paid for mainly. Now Ichigo Kurosaki, man, he makes a fortune, lives in a huge mansion in Malibu (why CA? well, because it's sunny there...apparently...). Same street as Naruto actually...Man those are some good acting skills...
Anyways, yes, Ichigo makes a lot of money as he is in every episode, but for talented actors such as myself, who get little screentime, we don't get paid quite so much. I spend most of my time relaxing, or just having a good time really... Anyways, the shop I own is great for me, as it helps pay the bills, what with my lack of screentime money that is...
Occasionally we do have a tight month. Providing for Tessai, and of course the kids, Jinta and Ururu is tough going. Takes quite a lot of money to provide for growing kids with mouths to feed. Anyways, Tessai has a part time job as a wrestler, so we make enough. However, when that Renji guy freeloads at our shop, it is tight.. *cries*, Why couldn't I have been a lawyer T_T
