Couple qualifiers about Trump being a business man, which is different from just being a 'capitalist' which these days includes financiers who produce nothing.
So he's a businessman distinct from just being a capitalist - he's a producer - of buildings - stone, steel and dirt ... which is why he's a blue collar guy. When the masonry sucks, it's on him as well as his mason. Also ... he's a NEW YORK business man. People from NYC don't flinch when he speaks as he does.
I think you make a good point that he is changing what America thinks of as good/acceptable presidential style. It's actually way more in tune with the rugged individualists - and producers before they were politicians - who founded the country.
But for the liberals ... anything but authenticity is all that matters.
I like this notion of “rugged individual”. It echoes Ayn Rand and I think that’s more in tune with a president like Teddy Roosevelt perhaps.
