We humans, endowed with the propensity for alertness and classified as Homo agens, act upon the information about what is valuable. Some are passive, only finding ways to increase their own happiness. Others are out there as profit seekers, and their actions benefit everyone.
These profit seekers try to identify the relevant ends-means framework and how to make it more efficient. Through their efforts to discover price differentials throughout the economy and along the time horizon they bring to the surface market knowledge. Their actions benefit themselves but also everyone else.
