StorminaBCup, I do exaggerate to make a point.
'So, why did he start a con university and sells his own name as brand to dodgy companies and then telling the conned people (who trusted the name) that he has nothing to do with them?'
Not to line his pockets, as Trump University is a tiny part of his business.
'Many (?most) previous presidents have/had enough personal wealth to not 'have' to work, yet they are more part of some kind of conspiracy than Trump?'
None of them has been as independently wealthy as Trump. He self-financed his primary run, the "career politicians" need millions of dollars in campaign contributions to fund attack ads against their opponents. They are in hock to lobbyists, nearly all the Republican lobbyists are anti Trump and were funding Establishment candidates like "low energy" Jeb Bush or Rubio or even Cruz when they realised that Trump was going to be exceedingly difficult to stop.
'but I truly do not get what makes you (and so upsettingly many others) think that Trump would be different'
Read interviews of Trump fans. They all say Trump is not Establishment, he is not "bought and paid for", no one "owns him" and he is not politically correct and therefore is anti the Establishment who all are politically correct. So basically, Trump is different to the Oxbridge, Harvard and lobbyist lot.
As Niall Ferguson, who is most probably anti Trump and an Establishment backer of Remain with Cameron and the rest of the Establishment, says in today's Sunday Times
"As the Fishtown hordes rally to Trump, Hillary’s elite risks coming apart
...
On the one hand there is a “cognitive elite”, who are educated together at universities such as Harvard, marry each other, work together and live together in the same exclusive neighbourhoods.
Concentrated in “super zip codes” such as Beverly Hills, Santa Monica, Malibu, Manhattan and Boston
