Do any of these cunts other than Orochi and that old judo guy have...like...
Jobs?
Kaoru Hanayama: Yakuza
Retsu Kaioh: 4000 year old chinese bank account, real answer: runs a school
Yujiro Hanma: does what he wants
Oliva: paid by government
Baki: inheritance from mom
Jack: either pit fighting, tokugawa, or he's the baki version of mr shakedown from yakuza 0. Considering how much he eats he probably goes to places where if you eat enough in a limited time you get it for free
