Each generation has its own characteristics and social culture.
The character of each generation influences the people inhabiting that generation:    The Silent Generation – Silence! Boomers – Thrifty Gen X – Independence Millenials – Socially Concious Gen Z – Authenticity

Each generation goes from cool to being out dated by the next one
In the digital age more emphasis is placed on dividing the generations into behaviours that can be compared, admired, mocked & ridiculed. Recent generations look back at the mess previous generations have left them to clear up.

Perhaps as we become more homogenised, with a view that we are quite similar to each other. The new generations have to show that they are different by making clear their own generations’ characteristics.

If modern culture is a big cauldron of soup: each generation offers up strong flavours of their own beliefs and attitudes: sometimes these flavours are so strong they are unpallatable. Eventually added to the modern culture soup they lose the intensity of taste. Yet go onto enhance the general taste of the soup more subtlely. To be marked by this intensity of our own generation’s experience: then see them waekened & stirred into the main cultural soup, with a newer generation arriving behind us – is a great loss.
Some are not able to come to terms with this loss: and remain with the politics, social cues, & cultural mores of their own generational experience.
So the seeds of nostalgia are born to fuel the fire of Populism.
