The First Law of Thermodynamics also known as the Law of Conservation of Energy, states that energy cannot be created or destroyed in an isolated system. Meaning what you put in it is what will come out.
In an ideal economic system, you’d expect that the effort you put in should equal the result of those efforts. The result/reward increase when you factor in the amount of risk taken along with other factors.
Yet we still have the debate about whether those who take all initial the risk and put in the effort should share the rewards of their labour with the rest of the world.
