I agree, except I think it goes back beyond 30 years.
Trump went to military cadet school prior to business school.
I think he was selected and fed/groomed intel probably about safe business deals, and info on his opponents, how to blend into the clique, Miss Universe pageants for example.
His interviews go way back where he stands out from the rest while being part of them.
I think he's been undercover most of his life.
