America had a boom then, and arguably so did europe in culture at least certainly. That said, much of europes economic generation, was the flower of whole nations youths being stolen by flanders fields - either literally in death or psychologically. Nevermind the social and political upheavals seen in around half of europe from WWI - Britain which escaped more unfazed than most of europe from physical damage, still had a mix of cataclysmic change and steady social progress (unwinding of the values and cultural norms of the victorian/edwardian era) - and also suffered vast amounts of deaths. National identities were formed too, Australia, Canada and New Zealand all or in part formed their national identities out of the cataclysm of WW I. This doesn't even account for the new nations formed all over Europe, The Middle East, and Africa because of The Great War.
