The sell is to individuals to get their votes, not corporations (who of course are on board, but cannot vote), and more amorphous for not being above board. About how people's hardship are being caused by "enemies" who must be punished. Thus the "cruelty is the point" observation.
Simply stating their goal, "the hyper rich feel too fettered, with respect to the rights/safety/wellbeing of individuals", would fail for being overly direct and honest.
