The kanji 稼 is a phono-semantic compound (形声文字, keisei moji). The radical on the left side is イネ (ine, 禾), which means "grain" or "rice plant." The right side is 家 (ie, meaning "house" or "family"). The origin of 稼 can be interpreted as the result of working in the field and bringing home the grain to support the family. It combines the idea of agricultural work related to harvesting with the concept of the home and family, suggesting that "earning" is tied to providing for the family's needs.
