I am also not from the US, but I really don't think any individual person (President) will make any difference, each and every one of them is subservient to vested interests and as much as they might want to fix something it is not in their power to do it. If you expect Trump to live up to his campaign promises I believe you are going to be very disappointed.
Frankbacon, he said he was going to put Hillary in jail I believe he already backed down on that, in fact I believe they are good friends. And if his credentials are firing people and claiming bankruptcy, boy there is going to be trouble ahead.
But as I said above regardless of who is President he is not really in charge and probably nothing will change, well maybe the rich will get even richer.
