You nailed it - perfectly. Had no idea you would see that impression in Greece too - thanks for educating me...
Years ago, we helped a family from Nigeria who won the Green Card lottery and were coming to the US. The lady sadly wasn't informed - but she literally thought the roads in the US were gold...
The impressions outside due to word of mouth and TV (world prior to the internet) - gave some incredibly warped impressions.
To your very good point -- how? how are in still living with these impressions when we have the internet?
Goes to show, the internet does not equate with a more educated and civilized populace. Sadly.
Thanks for reading and sharing your valuable thought - always, Benighted. ❧Hugs to you!! ☙
