Money in Naruto
Money in Naruto comes in the form of 'Ryo'. However, it isn't ever explicitly mentioned how money is received or created. For example, Kakashi Hatake. Previously, he was part of the ANBU Black Ops, then soon became a jonin-level, academy teacher. What kind of income did he get while he was working as an ANBU? If any? Compare him to a chunin, academy teacher like Iruka Umino. What kind of income did he get? If you compare them together, would that mean Kakashi is significantly wealthier than Iruka?
