I am taking a risk of giving the whole thing a weird approach, but why do we really need to TRUST our leaders? They are just government officials doing their job; and they are, they have been, and always will be only exponents of the financial influential elite of the society - so their job never had anything to do with us anyway. Except for three touching points when they need us : at election time, at tax collecting time, and at time to send us to give our lives for their ideas.
Leaders are a bad necessity, not idols in front of whom we should fall on our religious knees. It's an arrangement totally different from your marriage where you can talk about TRUST. Except for those crumbs of information heavily filtered by news media, we don't have a clue what's the real game being played.
So, how can we TRUST a player whose game we don't know? We don't have to DISRUST him either, His business is none of our business, since we don't really know the first thing how to run a country in its all gigantic complexity and dynamics that changes the face of the political stadium from day to day.
Donald Trump is a gutsy businessman, who may do well, if for no other reason but to be admired. Is that a shortcoming? Should he be ashamed for admitting his ambition and his confidence, and his belief that he can make a difference for his country? You show me a politician who SECRETLY doesn't feel about himself/herself the same what Trump is hanging high on the church's bell for everyone to hear.
I said it elsewhere and I will say it again: I am not his fan. But that doesn't mean that I would be disappointed to see him in the White House. For one thing, I am a Canadian, and neither way makes a difference to me. And then, I do admire his gutsiness, his resolve, even his ego. In a race where politicians will put their opponents down with white diplomatic gloves, he is replacing those gloves with the boxing ones - and that's the only difference.
You know what - maybe all of us could learn something from that man: to start loving ourselves more, so maybe we would not expect from a parental figure (leader) to be nice enough to us.
