If human history is taken as a reference point and compared with the current state of affairs (in all walks of life), we would find a clear pattern emerging between demand and supply. As far back as in 6000 BC, humans developed the barter system. With passing time, rules were created to accommodate complex transactions. As rudimentary as those regulations were in those times, their pace of development remained steady and was in direct correlation with ever-developing human acuity and urgency of demand.
