- The Heritage Foundation was part of the implementation.[1]
- Far more businesses hired lobbyists in Washington.[2] Business lobbying used to be a minor activity.
- Academic support was obtained. First, from Milton Friedman. See his famous article announcing that the social purpose of corporations is to increase profits.[3] This gave academic respectability to "Greed is good, greed works". Entire academic centers were purpose-built to push this position. The Mercatus Center at George Washington University is one such.[4] Other academic institutions were repurposed, through funding, to support this effort. The Hoover Institution is one of them.[5]
None of this is a secret, but it's not that well known.
