True story: I spotted Jack Dorsey 2 weeks rocking Balenciaga kicks and streetwear in Soho NYC. My point is fashion is just fashion and what you wear is relative to what you consider to be your "in group".
Some of the negative comments here exemplify why the mainstream is starting to hate on the "tech elitist" types in the same way FinanceBros were viewed negatively in the '90s and '00s.
I would add differences in domestic consumers preferences. Americans are now addicted to cheap-quality goods. I passed through the gift shop inside Empire Sate Building in NY yesterday and 98% of the gifts are asian imported plastic trinkets branded with Empire State and USA logos. Contrasts that to when I visited the museums in Berlin where the shops mainly focused on selling locally produced crafts.
