They say you can only be conned if you want something. ie You want that Rolex for cheap so you ignore that it likely isn't real or, at best, "fell off a truck". Trump provides them with cover for their racism, sexism, laziness, lust, greed, nastiness and they will overlook lots to get that.
It is sickening.
And they, and the rest of us against our will, are paying a heavy price for it! It's like, don't you even care about your own kids and grandkids? Being around brown people will not hurt them, not having health care or job prospects will!
They believe their children and grandchildren will be above all of that with the money they pass on to them. Rule of the oligarchs. Also a factor, they are shameless and think "why should I worry, I'll be gone".
