Apparently, 12 economic advisors were before Reagan.
Jack Kemp, apparently, was the main convincer, according to Irving Kristol.
Jack Kemp, in case you don't know, should be admired for his anti-racist stance.
But, as a football player, and a 2nd rate intellect, it is pretty obvious that we had a moron (Reagan) having a moron (Kemp) convincing intellectuals of the right of this idea.
For the record, Reagan was a hateful, spiteful racist, who went out of his way to rub salt in the wounds of the 1950s and 60s.
