Franklin uses a contrast between physical lightness and emotional or practical weight. A “light purse” means having little money, while the “heavy curse” is the hardship that can follow from financial scarcity. The saying points to the way a lack of resources can create pressures far greater than the small amount of money itself might suggest.

The quotation is less about wealth as a source of status than about the difficulties associated with not having enough. Limited means can restrict choices, make unexpected expenses harder to manage and create persistent anxiety about basic needs or obligations. Franklin’s compact phrasing turns an everyday object, the purse, into a measure of economic security. The broader point is that poverty or financial insecurity can weigh heavily on a person’s life, affecting independence, stability and peace of mind.
