I use the term "crank" affectionately. The figure below is a valiant effort by Arthur O. Dahlberg to depict the "socio-economic process" as a network of troughs, pipes and valves. Even this elaborate contraption is confined to "the movement of the major social variables." Dahlberg believed that his chart technique communicated his analysis more effectively than words could. What the chart communicates to me, besides Dahlberg's intense commitment is "it's complicated" and "everything is connected to everything else." That's not nothing.
