Do "the good times" depend on which nation you are from?

In the USA, the good old days tend to center on the 50s and 60s. Those were the "Happy Days." TV programs and movies, from "Mad Men" to "American Graffiti" are frequently about those days. In England, it often goes back to WW II and the years before - the 50s and 60s were rather grim. In France, it goes back several hundred years. Each country has a different version of the "good old days." We need to be aware of these differences as we travel or do business.
