Rejection Cost. From the perspective that my profit is someone else’s loss, and someone else’s profit is my loss, the fact that I have to reject an opportunity to make money for my circumstances is a loss for me and an act of giving someone else a profit. In other words, my added value is not determined solely by productivity but also by the marginal utility generated by the law of supply and demand. Therefore, my labor price should reflect the value that I have given up—the profit I could have gained. If the rejection cost is not included in my profit, I will be at a loss to that extent. Failing to account for rejection costs in production expenses is not wise, but foolish, because it risks my survival. There is no absolute value in this world. All economic values are relative. - Joseph’s “just my thoughts”
The first civilizations of mankind originated in arid climates. The Mesopotamian and Egyptian civilizations are examples. A city is relatively safe from infectious diseases if it is drier than wet. The key is water. It is a river where there is water while it is dry. Therefore, the shape and location of the river are important. A dry, watery zone is formed when the river flows from north to south. In other words, the city was born under the influence of disease. - Joseph’s “just my thoughts”
