In an interview with Politico on Wednesday, Gary Robbins, a Cain campaign consultant claimed that the candidate’s “9-9-9” plan would probably be “worth 15% in growth.” He then conceded that the plan would probably never be enacted, since people would be unwilling to accept such drastic changes.
“The problem with the big-bang changes like that, the flat tax or the fair tax, is that they are so alien to the current system that it would be a great big shock,” he said.
