You do realise that there's a world outside the United States, right? And that in Britain, Australia, Canada, New Zealand, all the other culturally similar countries, they also stopped wearing hats sometime in the 1950s and 60s? That public transport remains the main way for (say) Londoners to get to work, and yet that the hat slowly vanished from the heads of Londoners over roughly the same period that it vanished from the heads of Los Angelinos?
