As gen X, I'd agree with the first part about the 80s. The 90s were good too, but I think there was also some sense that it was all fake or a house built on sand or something — the 90s were the decade of Nirvana and The Matrix after all.

I don't generally subscribe to sweeping generalizations about eras being overall good or bad in the absence of data though. I'm not sure any decade of my life has been better or worse in any way that I could point to general societal trends (industry or major sector trends are different).
