These decline stories are universal, and probably no more true than 400 years ago: I am French and live in Hong Kong, do you think decline is not what everyone is talking about in BOTH places ? What is a place not in decline in the eyes of its inhabitants ?
It says more about how we view the past than how the present is: we remember only the glorious good times, and forget nobody could read 200 years ago, or nobody could eat 400 years ago. They all said they were in decline, the values of their grandfathers diluted by a constant change.
But while I sit on my toilets, on the 44th floor of my hyper tower, writing to americans in a language nobody in my ascending family can speak, before tucking my trilingual kid to bed, well, I think the decline isn't so bad, if you zoom out a few decades.
