Flows, Like Machines, Exist at All Levels of a Society

A river is almost never just some uninhibited stream of liquid that sort of meanders anywhere it happens to go. There's a specific reason river is moving in the direction that it is, at the speed that it is. For example, a glacier melting on the top of a mountain and gravity polling water to its lowest point. Like floes we can spot in society, there is always some sort of force responsible for why this flow exists between these two poles.
