It had never happened in what you say, if we look further, that has always happened, even in developed countries.
That has to do with the simplification of things, by simplifying it they lack identity and lose individualism, or culture, whatever you want to call it, that is why modern architecture is very straight and simple; not like the old one, well crafted and detailed.
Non avevo capito questo punto, ma hai ragione nelle caratteristiche dell'architettura moderna, vedi una nuova casa in campagna e sembra molto simile, questo è quello che devono cercare, abbinaci!
