Trump doesn't get it... And he never will.
Trump simply does not understand non-transactional life choices.
“He can’t fathom the idea of doing something for someone other than himself,” one of Kelly’s friends, a retired four-star general, told me. “He just thinks that anyone who does anything when there’s no direct personal gain to be had is a sucker. There’s no money in serving the nation.” Kelly’s friend went on to say, “Trump can’t imagine anyone else’s pain. That’s why he would say this to the father of a fallen marine on Memorial Day in the cemetery where he’s buried.”
