In electrical theory, potential difference—voltage—is what drives the flow of electrons, creating energy and power. Without it, nothing moves. The same is true for economies and societies. Progress happens when there are differences in opportunity, ambition, and reward—when there is potential to be realised. Just as excessive resistance blocks electrical current, overregulation and forced equality stifle economic growth. True prosperity comes from allowing energy to flow, not short-circuiting ambition.
