FYI I believe a 4T is a direct response to the ideals created during the 2T, with 1T/ 3T working as a bubble in between. Pop the bubble and it's like our post 9/11, middle Eastern wars and recession world is a continuation of the 70s.
Going back to the decadence of the 00s, I think people need to look at how people behaved and dressed as if the world wasn't falling apart, similar to how Scarlett O'Hara danced around as if nothing wrong during the Civil War, or how we had Dance marathons and happy musicals starring happy rich folks during the 30s. The early crisis is still an attempt to keep the illusion of the 3T alive and thats what deepens the crisis. Meanwhile, compare the popularization of hip hop in the 2000s with how Jazz became washed out and clean cut during the 30s. Our current eletcro dance scene is modern big band.
I think people in the 90s and 20s really did believe times were good and were not trying to escape.
I'm going to complete my ramblings by saying that I spoke to some late wave GI's and they didn't really feel the crisis of the 30s until maybe late in the decade.
