Fashions come and go. It is likely this one will as well. Just a matter of when.
How does climate explain changes in art the co-occur with political changes? Like when Alexander reached Asia, suddenly the sculptures there started resembling the ones they made in Greece.
Grand displays of wealth through luxurious materials nowadays are seen as egotistical, self-aggrandizing, and antiquated. Whereas modern design is a display of the good taste and international character of someone who appreciates sleek elements yet has enough money to buy spaces that are largely empty.
Or the interiors of ordinary people's houses in places like Morocco? Or the cafe down the road where I get 'Indian breakfast' for £3? (Channa/naan and tea made with spices).
These are aren't mutually exclusive.
But suffice it to say people just happen to have similar opinions about fashion, religion, ideologies, etc. as what is needed to fit in and global media has accelerated the process. The fact that people like stuff isn't in question, but we're amazingly good copy machines for reasons that helped us become the dominant species on the planet.
