The thesis is predicated on a framing that makes no sense.

Gordon Gekko did not influence Wall Street. Capitalism’s functional stages are a product of conventional strategies and the predictable capture of political power by financial power.

Wall Street’s current form was articulated in volumes I and III of “Capital” by Karl Marx. That profit diverges from value, competition leads to consolidation, speculation generates profits which are derived from unrealized market growth which has to continually borrow against itself and uses as its final bank the stability of a coercive state (which it eventually depletes)
