Only when there is a surplus can new things be created. Surplus means having more than what is necessary. Creating something new requires an initial investment in advance. Whether it’s labor or capital—that is, whether labor is purchased with capital—energy can only be used for new work if there is a surplus. Only with prior investment can something entirely new, never seen before, be made. The existence of something that did not exist before in this world results from someone putting in their surplus first. - Joseph’s “just my thoughts”
A big supermarket can do business in the suburbs because of wheels. If someone asked me what is one of the greatest inventions in human history that civilization has ever developed, I would say "wheels." The automobile is also a wheel. Shopping carts are also wheels. Without wheels, how many people would go far and carry heavy loads? Mass distribution is possible because of wheels. To do bulk sales, you have to have a lot of inventory. That means you need a lot of storage space. It also means you need cheap real estate. The trivial circle, the wheel, is the key to solving all these constraints in one shot. - Joseph’s “just my thoughts”
