The business ecosystem, like biological ecosystems, involves forms of collective life that have learned how to sustain themselves in competitive environments, usually by seeking moats. Those moats "rig the game". The moats tend to fail when the environment changes; e.g. due to technical innovation, social movement, external shocks. It is the central interest of any business to build moats and drawbridges.

Life is turtles all the way down and drawbridges all the way up. Anyone seeking opportunities is looking for the openings between those moats and drawbridges.
