Is what pronounced binbo? 貧乏 [びんぼう - binbou] means "poor" as in having no money, if that's what you mean.

Well, fishermen were pretty high-class people in feudal Japan, on the level of rice farmers -- both of which had much higher status than merchants, artisans, etc., and were just below samurai in the class hierarchy. Actually, merchants were the lowest of the recognized classes. Below merchants were the classless, the social outcasts, such as burakumin (部落民), people who dealt in unclean or tainted trades (for instance, tanners or butchers).
