I moved from Germany to the US a long time ago and at first I was confused by what you call "good vibe culture". I've come to appreciate it, though. When I visit Germany now I notice that people make less of an effort to keep surface interactions more polite and often make a point of spreading their bad mood around.
Beyond the surface interactions there's not much difference, though. Interactions with people you know better, be it friends, family or coworkers, are pretty similar.
But how real are the "good vibes"? The impression I get is a lot of the time its all just a facade.
When taken to the extreme you end up with a Potemkin village where everyone grins and nods and goes about their day never expressing anything honest.
I much prefer a society where people are open and there is some accountability than a group of smiling yes men which is the type of thing these corporate culture workshops seek to indoctrinate.
