A Duke University teacher has proposed a clarification for why the income difference in America between the rich and poor keeps on developing. It is, he says, because of the laws of physics.

 "The laws of physics show how things put in motion, and nothing moves unless it is pushed," said Adrian Bejan, educator of mechanical engineering and materials science at Duke University. "Pushing requires power, and power requires fuel, regardless of whether it is food that powers or fuels the human body or gas that fuel vehicle. Furthermore, the amount of fuel devoured or consumed by a country is directly connected with its financial development. So, physics and economics are two sides of a similar coin," as per Dukechronicle.

 The Physics law dictating income difference and many other phenomena is one that Bejan identified in 1996. The constructal law expresses that in order to survive, any streaming or flowing system must evolve to increase its access to flow. For instance, the human circulatory system has worked to give blood flow access through a couple of substantial or large arteries that branch into many small capillaries. River systems and trees demonstrate a similar evolution, ScienceDaily reported.

Bejan contends in the Journal of Applied Physics newspaper dated March 28, 2017, that a similar natural tendency controls the flow of goods, services and income or money on the earth's economies. As time advances and social orders evolve, movement and energy consumption develop and economic distinction or disparities naturally become greater. There is, in any case, a warning.

 "As wealth inequalities develop or grow, the society demands greater equality," said Bejan. "With developed delegate governments, laws are passed to push the line back toward greater equality.However, as time goes by, the inequality starts to develop again and people are constantly inquisitive with respect to why inequality is hard to eradicate or erase. This phenomenon is a natural law of physics, and as such, it cannot be prevented."

 "Certainly, a few governments have attempted to dictate equality overnight, prompting to grievous outcomes or results," Bejan said. "Simply take a look at the Bolshevik Revolution. During the time of trying to established universal equality, there were at that point government insiders and party leaders who had tremendous power and riches. Today in Russia oligarchs have the riches. Physics always wins.
