This quote is a metaphorical observation about the nature of power and the dynamics of leadership. In a river, the lightest things float on top, while heavier things sink to the bottom. This is a physical fact. Franklin uses this as a metaphor for bad governments, suggesting that in such situations, those with less substance, depth, or quality—symbolized by lightness—rise to positions of power and visibility, while those with more substance and quality—symbolized by heaviness—remain unseen and unappreciated.

This quote is a critique of poor leadership and governance. It implies that those who are less competent, less experienced, or less qualified often rise to power in poorly run governments, while the more competent, experienced, and qualified individuals do not. This can lead to a variety of problems, including corruption, inefficiency, and a lack of progress.

In today’s world, this quote could be applied to any system or organization, not just governments. It suggests that we should be wary of those who rise to power too quickly or easily, as they may lack the depth and substance needed to lead effectively. It also suggests that we should value and seek out those who have the depth and substance to lead, even if they are not the most visible or outspoken.

In terms of personal development, this quote could be a reminder to not be swayed by superficial appearances or quick fixes. It encourages us to seek depth and substance in our own character and abilities, and to value these qualities in others. It reminds us that true quality and worth is often found beneath the surface, and that we should strive to recognize and cultivate these qualities in ourselves and others.
