Trump is the first American president who was a businessman. All those before him were born to it, raised to it, spent their whole lives living it: the Ivy League.
Trump was a - I suppose self taught - wealthy business man who could not get any higher than he was, so having the money, he ran for president and won.
He won because he was able to talk down the the American working - I suppose the lower echelons mostly - for him understood his childish speaking manner and the way he addressed them as employer to employee. They were familiar with that. They understood it. He went over and over some words. He used slang and filler words thinking that they were what the working man understood better than the cultured manners of previous election candidates.
It would not have worked with me, and probably all the British and European voters, because we do not primarily choose our MPs by how much money they have and how much control they have over their workforces.
The problem with Trump is that he treats other people - including heads of state in the same way.
Worse though he insults their intelligence. I listened to the press meeting in the White House with the German Chancellor. It was all about Trump, what he wanted, what he did, and constant repetition. Is he incapable of learning anything about the world leaders he invites to America? Nothing he has said so far to any of them had any meaning at all.
That is what will destroy Trump eventually. It will not be tolerated by the people of America and the world for long, because too much is at stake.
